Percentile ProjectionsBased 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

Student scores are confidential. Therefore the example below is merely a simulation model. None of the score data displayed below is real.

More About TVAAS Percentile ProjectionsPercentile scores are not percentages! 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 80% of all the students that took that same test.

Slide 2

How to Use These Percentile ProjectionsI recommend that you convert them into percentage scoreswhich are commonly used by many teachers for scoring quizzes and testsPerhaps 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 yearQuick 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 studentsOnce you have your conversion table, make a list with this year's student's names

Slide 3

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 percentagesUse the percentage projections as target goals with your current studentsFor any and every appropriately aligned quiz or test, you can challenge your current students to earn a score equal or greater than the projected scoreYou may even find it helpful to inflate the projection by a few percentage points to make sure you are adequately challenging your studentsIf you can enable your students to consistently earn a score equal or higher than their projected score then it is very probable that they will show growth with the TCAP test
