PVAAS – The Thanksgiving Edition Did your Thanksgiving Dinner Meet the minimum expectations this year? Whether it met the expectations or not was it better than the year before?

Essential Question How can PVAAS be used by teachers and administrators for annual school, grade, subject, and student evaluation and planning?

PVAAS has Two Methodologies 1. Value-added Analysis for growth in cohorts of students by school, grade, subgroup. 2. Projection capability to calculate the likelihood of a student achieving a specified target performance level on a future PSSA test.

Current Data Collection Approaches High Achievement Average Achievement Low Achievement ( Achievement is based on each student’s ending point )

PVAAS Adds Another Value To Achievement…Progress Below At or AboveGrowth Standard ( Progress is based on each student’s starting point )

How to Measure Growth Student scaled scores are converted to NCE scores The mean NCE score for each school is calculated PVAAS revises all earlier estimates based on the addition of the current data PVAAS calculates an estimated NCE mean score

Okay… What “the heck” is an NCE Score? An NCE score indicates the position of a scaled score on a reference scale (mean =50, sd=21.06) z-score = Observed – Mean/SD [basically you are calculating the number of standard deviations the data value is from the mean of its distribution] This allows the scaled score from different distributions with different scales to be compared

R* - Estimated mean NCE gain below growth standard by at least two standard errors. To view additional reports, click on the underlined numbers or words.

Projection Summary Tool PVAAS will allow you to identify students who need extra support in preparation for a future PSSA Projections are based on a combination of Math and Reading scores over time

Projection Ranges 0% - 40%Not likely without significant intervention programs 40% - 70%Could be successful with intervention programs 70% - 100%Likely to be successful with maintaining current program
