The goal of teacher evaluation
The ultimate goal of all teacher evaluation should be…
TO IMPROVE TEACHING AND LEARNING

Part 1: An Overview of Teacher Quality, Teacher Effectiveness, and Teacher Evaluation
4 www.tqsource.org
What the evidence says about teacher quality (Goe, 2007)
Experience matters, but only for the first five years or so as teachers learn on the job; After that, experience adds little in terms of student achievement Teachers’ subject matter knowledge (as evidenced by course-taking) appears to contribute significantly to math achievement, particularly at the secondary level, but research has not convincingly demonstrated that it matters in other subjects Subject matter certification contributes significantly to math achievement, but is not significantly and consistently related to student achievement in other subjects 5 www.tqsource.org
Research Behind the Push for New Evaluation Measures and Systems
The Widget Effect report (Weisberg et al., 2009) “…examines our pervasive and longstanding failure to recognize and respond to variations in the effectiveness of our teachers.” (from Executive Summary) Value-added research shows that teachers vary greatly in their contributions to student achievement (Rivkin, Hanushek, & Kain, 2005).

Keys to Measuring teacher Effectiveness
Measure what is required legislation and incentives) (i.e., federal/state Measure what is valued expect teachers to do) (i.e., all the things we Develop and make available to teachers and evaluators the standards by which teachers will be evaluated Familiarize teachers with tools and processes of the evaluation Measure performance against the standards 7 www.tqsource.org
Race to the Top definition of effective & highly effective teacher
Effective teacher: students achieve acceptable rates ( e.g.
, at least one grade level in an academic year) of student growth (as defined in this notice). States, LEAs, or schools must include multiple measures, provided that teacher effectiveness is evaluated, in significant part, by student growth (as defined in this notice). Supplemental measures may include, for example, multiple observation-based assessments of teacher performance. (pg 7) Highly effective teacher students achieve high rates ( e.g.
, one and one-half grade levels in an academic year) of student growth (as defined in this notice). 8 www.tqsource.org
Race to the Top definition of student achievement
Student achievement means— (a) For tested grades and subjects: (1) a student’s score on the State’s assessments under the ESEA; and, as appropriate, (2) other measures of student learning, such as those described in paragraph (b) of this definition, provided they are rigorous and comparable across classrooms. (b) For non-tested grades and subjects: alternative measures of student learning and performance such as student scores on pre-tests and end-of-course tests; student performance on English language proficiency assessments; and other measures of student achievement that are rigorous and comparable across classrooms.

Race to the Top definition of student growth
Student growth means the change in student achievement (as defined in this notice) for an individual student between two or more points in time. A State may also include other measures that are rigorous and comparable across classrooms. (pg 11)

What standardized tests can’t tell you
Standardized tests can’t tell you why students in a particular classroom are scoring high • Maybe there is a narrow instructional focus on test content • Or maybe the classroom offers a rich, engaging curriculum that fosters deep student learning
How
teachers are getting results matters, not just the results themselves 13 www.tqsource.org
Measures of teacher effectiveness
Evidence of growth in student learning and competency
• Standardized tests, pre/post tests in untested subjects • • • Student performance (art, music, etc.) Curriculum-based tests given in a standardized manner Classroom-based tests such as DIBELS
Evidence of instructional quality
• Classroom observations • Lesson plans, assignments, and student work
Other evidence (varies, based on local values)
• Administrator/supervisor reports • Surveys of students and/or parents • An “evidence binder” created & presented by the teacher 14 www.tqsource.org
Evidence binders
Teachers collect and organize evidence that demonstrates their proficiency and/or indicates progress in • • • Classroom practice Professional/out-of-class activities Student learning linked to teacher practice Teacher assignment + student work Teacher assignment + set of student work showing growth Pre- and post-test scores showing student progress DIBELS and other classroom-based tests 15 www.tqsource.org

Growth-oriented evaluation
Many evaluation systems currently in use ignore growth opportunities for teachers who are “doing fine” For teachers who are struggling, the “help” may be seen as punitive rather than as creating opportunities for teachers to improve practice But some measures of teacher performance are far more useful than others in helping teachers to improve their practice, which will in turn improve student learning 17 www.tqsource.org
Measures that help teachers grow
Measures that motivate teachers to examine their own practice against specific standards Measures that allow teachers to participate in or co-construct the evaluation (such as “evidence binders”) Measures that give teachers opportunities to discuss the results with evaluators, administrators, colleagues, teacher learning communities, mentors, coaches, etc.
Measures that are directly and explicitly aligned with teaching standards Measures that are aligned with professional development offerings Measures which include protocols and processes that teachers can examine and comprehend www.tqsource.org

Austin Independent School District
Student Learning Objectives:
Teachers determine two SLOs for the semester/year One SLO must address all students, other may be targeted Use broad array of assessments Assess student needs more directly Align classroom, campus, and district expectations Aligned to state standards/campus improvement plans Based on multiple sources of student data Assessed with pre and post assessment Targets of student growth Peer collaboration 21 www.tqsource.org

23 www.tqsource.org
SLO Model Strengths/Weaknesses
Strengths Teachers take an active role in determining student learning goals Good professional growth opportunity for teachers If objectives are of high-quality and teachers plan instruction to meet them, students should benefit Weaknesses Heavily dependent on administrator understanding and time commitment to supervision Not clear how or if “rigor” could be determined Not “comparable across classrooms” because teachers set the objectives and they will vary widely Not clear how students’ beginning point is determined 24 www.tqsource.org
“Rhode Island Model” is another example of an SLO Model
Under consideration, not yet implemented • • Teachers measure student growth by setting student academic goals aligned to standards Principals, during the goal setting process, will confer with teachers to establish each goal’s degree of ambition and select the appropriate assessments for measuring progress against the goals • Teacher evaluation will be based on students’ progress on the established goals, as determined by an end-of the-year principal review of the pre-determined assessments and their results 25 www.tqsource.org

Impact on student learning Professional Practice (including content knowledge) Professional Responsibilities “…each teacher’s Student Learning (SL) rating will be determined by a combination of state-wide standardized tests, district-selected standardized tests, and local school-based measures of student learning whenever possible.” 26 www.tqsource.org
RIDE Model: Impact on Student Learning
Category 1: Student growth on state standardized tests that are developed and/or scored by RIDE Category 2: Student performance (as measured by growth) on standardized district-wide tests that are developed and/or scored by either the district or by an external party but not by RIDE (e.g., NWEA, AP exams, Stanford-10, ACCESS, etc.) Category 3: Other, more subjective measures of student performance (growth measures and others, as appropriate) that would likely be developed and/or scored at the district- or school level (e.g., student performance on school- or teacher-selected assessments, administrator review of student work, attainment of student learning goals that are developed and approved by both teacher and evaluator, etc.) 27 www.tqsource.org

Professional responsibilities rating Final evaluation rating The student learning rating is determined by a combination of different sources of evidence of student learning. These sources fall into three categories:
Category 1
on state tests (e.g., NECAP, PARCC) : Student growth standardized
Category 2
: Student growth on standardized district-wide tests (e.g., NWEA, AP exams, Stanford 10, ACCESS, etc.)
Category 3
Other local school-, or teacher selected student performance : administrator-, measures of 28 www.tqsource.org
“‘Rhode Island Model”: Student Learning Group Guiding Principles
•
“Not all teachers’ impact on student learning will be measured by the same mix of assessments, and the mix of assessments used for any given teacher group may vary from year to year.” Teacher A (5 th grade)
Category 1 (growth on NECAP) + Category 2 (e.g., growth on NWEA) + Category 3 (e.g., principal review of student work over a six month span) =
Teacher A’s student learning rating Teacher B (11 th grade English)
Category 2 (e.g., AP English exam) + Category 3 (e.g., joint review of critical essay portfolio) =
Teacher B’s student learning rating Teacher C (middle school art)
This teacher may use several category 3 assessments
29 www.tqsource.org
“Rhode Island Model” Strengths and Weaknesses
Strengths • • Includes teachers in evaluation of student learning (outside of standardized tests) Teachers will benefit from having assessment of student learning at the classroom level Weaknesses • • Heavily administrator/evaluator driven process Teachers can weigh in on assessments, but do not determine student growth 30 www.tqsource.org
Teacher Advancement Program (TAP) Model
TAP requires that teachers in tested subjects be evaluated with value-added models All teachers are observed in their classrooms (using a Charlotte Danielson type instrument) at least three times per year by different observers (usually one administrator and two teachers who have been appointed to the role) Teacher effectiveness (for performance awards) determined by combination of value-added and observations Teachers in non-tested subjects are given the school wide average for their value-added component, which is combined with their observation scores 31 www.tqsource.org
TAP strengths/weaknesses
Strengths • • • Value-added becomes everyone’s responsibility, which should encourage efforts from teachers in non-tested subjects to support teachers in tested subjects Multiple yearly observations should be more informative and produce more reliable information about practice Professional development aligned with results is required Weaknesses • • Concerns about “fairness” when only a few teachers’ student achievement and progress toward learning goals “counts” Tells you nothing about how teachers in other subjects are performing in terms of student learning growth (grades are not always good indicators) 32 www.tqsource.org
IMPACT sorts teachers into groups that are evaluated differently
Group 1: general ed teachers for whom value-added data can be generated Group 2: general ed teachers for whom value-added data
cannot
be generated Group 3: special education teachers Group 4: non-itinerant English Language Learner (ELL) teachers and bilingual teachers Group 5: itinerant ELL teachers Etc… 33 www.tqsource.org
IMPACT components for Group 1
Individual Value-Added (IVA) = 50% of score Teaching and Learning Framework (TLF) (measure of instructional expertise) = 40% of score Commitment to the School Community (CSC) (measure of the extent to which you support your colleagues and your school’s local initiatives) = 5% of score 34 www.tqsource.org
IMPACT components for Group 2
Teaching and Learning Framework (TLF) (measure of instructional expertise) = 80% of score Non-Value-Added Student Achievement Growth (NVA) = 10% Commitment to the School Community (CSC) (measure of the extent to which you support your colleagues and your school’s local initiatives) = 5% School-wide value-added = 5% 35 www.tqsource.org
Explanation for 10% for test scores for Group 2 and others
“As a school system, we recognize that we still have a significant amount of work to do to establish norms for student achievement growth outside of the DC CAS grades and subjects. In recognition of this fact, we have decided to limit this component to just 10% of the overall assessment. As we develop clearer norms, we plan to increase this percentage.” 36 www.tqsource.org
Group 2 assessment rubric
3 “cycles” of data collected & averaged/year Highest level of rubric: • “Teacher has at least 1 high-quality source of evidence (i.e., one that is rigorous and reliable) demonstrating that approximately 90% or more of her/his students are on track to make significant learning growth (i.e., at least a year’s worth) towards mastery of the DCPS content standards over the course of the year.” 37 www.tqsource.org
Non-VAM tests (accepted under Washington, DC’s IMPACT evaluation system)
DC Benchmark Assessment System (DC BAS) Dynamic Indicators of Basic Early Literacy Skills (DIBELS) Developmental Reading Assessment (DRA) Curriculum-based assessments (e.g., Everyday Mathematics) Unit tests from DCPS-approved textbooks Off-the-shelf standardized assessments that are aligned to the DCPS Content Standards Rigorous teacher-created assessments that are aligned to the DCPS Content Standards Rigorous portfolios of student work that are aligned to the DCPS Content Standards 38 www.tqsource.org
DC IMPACT Strengths & Weaknesses
Strengths • • • Uses multiples measures to assess effectiveness Permits the use of many types of assessment for students in non-tested subjects and grades Includes what is important in the system (in order to encourage specific teacher behaviors) Weaknesses • • No multiple measures of student learning growth for teachers in tested subjects and grades Huge differences in how teachers are measured 39 www.tqsource.org
Georgia KEYS

Georgia KEYS for Non-tested subjects
41 www.tqsource.org
Georgia KEYS Strengths & Weaknesses
Strengths • • Rubric for measuring teacher contribution is easy to understand Includes examples of multiple measures of student learning for all teachers, including those in tested grades and subjects Weaknesses • • Rubric (including observation and other information) is about 100 pages long Might be a challenge to implement 42 www.tqsource.org
Delaware Model
Standardized test will be used as part of teachers’ scores in some grades/subjects “Group alike” teachers, meeting with facilitators, determine which assessments, rubrics, processes can be used in their subjects/grades (multiple measures) Assessments must focus on standards, be given in a “standardized” way, i.e., giving pre-test on same day, for same length of time, with same preparation Teachers recommend assessments to the state for approval Teachers/groups of teachers take primary responsibility for determining student growth State will monitor how assessments are “working” 43 www.tqsource.org
Delaware Model: Strengths & Weaknesses
Strengths • • Teacher-driven process (assumes teachers are the experts in assessing their students’ learning growth) Great professional growth opportunity as teachers work together across schools to determine assessments, score student work, etc. Weaknesses • Validity issues (how the assessments are given and scored, teacher training to score, etc.) • Time must be built in for teachers to work together on scoring (particularly for rubric-based assessments) 44 www.tqsource.org
Questions to ask about models
Are they “rigorous and comparable across classrooms”?
Do they show student learning growth “between two points in time”?
Are they based on grade level and subject standards?
Do they allow teachers from all subjects to be evaluated with evidence of student learning growth?
45 www.tqsource.org
Questions about Part 2?
46 www.tqsource.org
Part 3: Measuring Teachers’ Contributions to Student Achievement Growth in Non-Tested Subjects and Grades
47 www.tqsource.org
Evidence of growth in student learning
Evidence is strongest when it is • Standardized, meaning that all teachers used the assessment in exactly the same way Gave the assessment on the same day • • Gave students a specific amount of time to complete the test Used the same preparation/instructions prior to the test Recorded/reported results accurately Valid, meaning that it measures what is intended Items (questions) accurately capture students’ understanding and knowledge Progress towards proficiency in a subject is captured because there are sufficient items to measure students at all levels Recorded, meaning that student progress can be compared across classrooms and schools 48
Standardization is key
Standardizing how curriculum- or classroom based tests are given is key to ensuring that tests are “rigorous and comparable across classrooms” Ensure that tests meet district approval For subject-matter tests, ensure that • • Tests are given on the same day, at the same time, for the same length of time, with supervision Teachers agree to appropriate “test prep” rules 49 www.tqsource.org
Challenges for Special Education Teachers and ELL Specialists
Challenges for SWD and ELLs • Small student numbers • • • • • Not all special educators and ELLs instruct students in tested subjects Teacher contribution to social and behavioral growth would not be factored into results Teachers working with students on alternate standards Little research exploring whether growth rates are comparable Little research on the use of accommodations & their impact related to teacher effects 50 www.tqsource.org
Evaluating Teacher Effectiveness in Classrooms w/ Co-Teaching
Majority of SWD are in the general education classroom Various co-teaching models make it difficult to evaluate teachers • For example, teachers as aides or working with small group of students Who gets “credit” for student growth when there are multiple teachers?
51 www.tqsource.org
The teacher’s “caseload”
For nurses, counselors, librarians, and other professionals who do not have their own classroom, what counts for you is your “caseload” • • • • May be all the students in the school May be a specific set of students May be other teachers May be all of the above!
52 www.tqsource.org
Other teachers with “caseloads”
For team teachers, special ed teachers, ELL teachers, other itinerant teachers • • • Caseload would be the students you provide instruction or assistance to When students are shared between two teachers, those students belong to teachers’ caseloads both This may be done as a percentage, or the shared student scores would be counted for each teacher 53 www.tqsource.org
Student “demonstrations”
Using the term “demonstrations” to distinguish this measure from “performance” which is interpreted various ways Demonstrations: students demonstrate their proficiency by giving a performance (dance, music, drama, art, speech, etc.) or by creating and displaying something (artwork, a bookshelf, etc.) 54 www.tqsource.org
Guidelines for recommending measures
Measures must show students’ growth between two or more points in time Measures must be “comparable across classrooms” • • All teachers in that grade/subject should agree on what measures should be used Common rubrics, and agreement as to how they will be used Measures must be “rigorous” • Based on appropriate grade-level standards Measures should improve teaching & learning 55 www.tqsource.org
Multiple measures
Multiple sources of evidence of a students’ learning provide • • The teacher with better evidence about what the student knows and is able to do, allow him/her to adapt instructional strategies accordingly The evaluator with better evidence about a teachers’ contribution to student learning Results from a rubric-based assessment and results from a standardized test may show different aspects of a students’ knowledge and skills 56 www.tqsource.org
Quote from Arne Duncan re: Race to the Top
"We need to be tight on goals and loose on means." Laura’s interpretation • • • Chief goals are improving teacher effectiveness and increasing student achievement HOW we achieve those goals is less important (to Arne) than the fact that we DO achieve them We should focus as much as possible on measures that we believe will improve teaching and learning, rather than on blind compliance 57 www.tqsource.org
