School Value-Added

How This Report Helps You

The Value-Added 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.

For more information about changes to reporting, see Statistical Models and Business Rules.

About Value-Added Reports

School Value-Added reports provide reliable measures of the average academic growth a school's students made in each tested grade and subject or course. The growth measures indicate how successful the school was in helping students meet expected growth. 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 effectiveness of the school's programs.

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.

How We Measure Growth

The model we use to calculate growth measures depends on the assessments administered. Concept of Growth provides additional details.

Gain Model

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

  • K-2 assessments
  • EOG reading in grades 3 through 8
  • EOG math in grades 4 through 7
  • EOG math in grade 8 before 2022-23
Predictive Model

This analytic model is used for subjects that are assessed in non-consecutive or consecutive grades, including when students move from one assessment type to another:

  • EOG science in grades 5 and 8
  • EOG math in grade 8 starting in 2022-23
  • EOC Math 1, Math 3, Biology, and English II
  • CTE post-assessments
  • ACT, PSAT, and SAT

The Value-Added reports for ACT, PSAT, and SAT are intended to provide measures of how effective the school has been in the tested subject areas across grades, from the time students entered the school to the time they took the assessment. With that in mind, only EOG assessments are included in the students' testing histories in these analyses.
