How This Report Helps You

This report enables you to select data of interest, assess trends over time, and compare results. Use the filters on the left to explore growth and achievement data. Depending on the assessment, achievement is reported in Normal Curve Equivalents (NCEs) or scale scores and does not reflect proficiency level.

For step-by-step instructions on using the filters, see Interacting with the Report.

About Value-Added Reports

LEA/District Value-Added reports provide reliable measures of the average academic growth a LEA/district's students made in each tested grade and subject or Keystone content area. The growth measures indicate how successful the LEA/district was in helping students meet the growth standard. The value-added reports can help educators identify relative strengths and areas of concern across grades and subjects. When sufficient data is available, the reports include three years of growth measures and a three-year average growth measure. Examining patterns and trends across years can offer important insights into the academic growth of groups of students for the school's programs.

PVAAS uses PDE's Data Attribution Rules to determine how to assign students to schools. A minimum of 11 students is required to generate a district or school value-added report for a tested grade and subject or Keystone content area.

Students who are identified in the state assessment booklet as one or more of the following are excluded from the value-added analyses.

  • Not enrolled for a full academic year (by Oct 1)
  • First year of English language
  • Foreign exchange

In addition, students who took the Pennsylvania Alternate Assessment (PASA) or who previously performed at a proficient or advanced level on the same Keystone content area are excluded.

It's important to view the value-added reports in conjunction with the diagnostic reports, which display patterns of growth for groups of students at different achievement levels.

For more information about Keystone courses and specific enrollment scenarios, see Including Retester's Keystone Scores in LEA/District and School Growth Calculations.

How We Measure Growth

The model we use to calculate growth measures depends on the sequence of assessments administered. Concept of Growth provides complete descriptions of the models.

Growth Standard Methodology

This analytic model is used for subjects that are assessed in consecutive grades.

  • PSSA math and ELA in grades 4 through 8
  • Acadeince, aimsweb, DIBELS, EasyCBM, Exact Path, FastBridge, i-Ready, MAP, STAR
  • CDT Math, Reading, and Science in grades 4-8
Predictive Methodology

This analytic model is used for subjects that are not assessed in consecutive grades (in other words, when students move from one assessment type to another or when students take the assessment in different grades):

  • PSSA science in grades 4 and 8
  • Keystone Algebra I, biology, and literature
  • CDT Algebra I, CDT Biology, CDT English Language Arts grades 9, 10, and 11
