Why a vocabulary
lesson?
'My teacher said the school has tough new
standards and I need to improve my
vocabulary. What's 'vocabulary'?'
OBJECTIVES
Establish a common language
 Clear understanding by all
Better communication
 About processes
 About results
 About student achievement/failure
 About instructional practices that yield learning

Two Major Types of Tests
Norm-Referenced Test
(NRT)
Criterion-Referenced Test
(CRT)
What is a Norm-Referenced Test
(NRT)?
• A standardized
assessment in which
all students
perform under
the same conditions.
• It compares the performance of a student or
group of students to a national sample of
students at the same grade and age, called the
norm group.
What is a Criterion-Referenced
Test (CRT)?
• An assessment where a student's
performance is compared to a specific
learning objective or performance
standard and not to the
performance of other students.
• It tells us how well students are
performing on specific goals or content
standards rather than just telling how
their performance compares to a norm
group of students nationally or locally.
Question:
In criterion-referenced assessments, is it
possible that none, or all, of the students will
reach a particular goal or performance
standard?
Answer:
YES!!!

Three Major Types of Scores
Raw Score (RS)
• The number of items a
student answers correctly on
a test.
– John took a 20 item
mathematics test (where each
item was worth one point) and
correctly answered 17 items.
– His raw score for this
assessment is 17.
Question:
If Mary answered 24 items
correctly on a
Reading Test
24
reading test, and
40 items correctly on a
mathematics test, did she do
better on the mathematics
test than on the reading
measure?

Scale Score (SS)

raw scores
that use a new, arbitrarily chosen scale to represent
levels of achievement or ability. They have no inherent
or readily apparent meaning.
• For FCAT-SSS, a computer program is used to analyze
student responses and to compute the scale score. It
reports test results on the student’s entire test.
Scale Score (SS)
• Higher scale scores indicate higher
proficiency.
• On a continuous, vertical scale across grade
levels you can track a student’s progress from
lower to upper grade levels on one scale.
Growth in scale score units indicates growth in
proficiency.
• For FCAT-SSS, the Developmental Scale
Score is used to determine a student’s annual
progress from grade to grade.
Gain Scores
• Commonly
referred to as
“Learning
Gains”.
• The amount of
progress a
student makes in
one school year.
