Percentile Projections
Based on past testing history in your subject area and all other tested subjects
areas over the last 3 to 5 years
 Is computed by SAS as a projection of what this student is likely to score if he
or she receives an average education from an average teacher for this subject at an
average school in Tennessee

More About TVAAS Percentile Projections
Are percentile scores and not percentages! (They are not the same thing)
 Percentiles are determined by graphing all the score data in a normal curve
distribution (a bell curve).
Example: A student that scored in the 80th percentile scored equal or higher than
(see image below)
80% of all the students that took that same test.

How to Use These Percentile Projections
I recommend that you convert them into percentage scores
which are commonly used by many teachers for scoring quizzes and tests
Perhaps the easiest and most accurate way to do this is to simply use
your student's TCAP Quick Scores from last year along with their actual
TCAP scores from last year
Quick Scores have already been converted into percentage format for us
 Make a chart showing each student's Quick Score. Then match that
student's name with what he or she actually scored on the TCAP test.
Then delete all the names and student ID numbers, fill in the gaps, and
you will have a valid conversion table for percentages to percentiles to use
for this year's students
Once you have your conversion table, make a list with this year's
student's names

How to Use These Percentile Projections (Continued)
Use the current projected scores report from TVAAS to obtain the
percentile projections for your current students
 Use your conversion table created from last year's data to convert these
percentiles into percentages
Use the percentage projections as target goals with your current students
For any and every appropriately aligned quiz or test, you can challenge
your current students to earn a score equal or greater than the projected
score
I recommend that you inflate the projection by 5 to 10 percentage points
to make sure you are adequately challenging your students
If you can enable your students to consistently earn 5 to 10 points above
their projected score then it is very probable that they will show growth
with the TCAP test 

You can View TVAAS Student Projections Two Ways: (1) View Individual Student
Reports (as shown below), or view all students in a single spreadsheet format (I have
instruction for the spreadsheet format in a separate PP presentation.
