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.

OST Accountable reports include only those students accountable to that school.

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

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.

When you open a School value-added report, you see these options on the Tests/Subjects tab:

  • Tested: This option categorizes students based on the district, school, and grade in which they tested in the reporting year.
  • Accountable: This option categorizes students based on the district and school that are accountable for the student's learning. If a student did not attend one school long enough for the school to be accountable, the district is accountable. If a student did not attend school within one district long enough for the district to be accountable, the state is accountable.

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.

  • OST mathematics, English language arts, and composites in grades 4 through 8
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:

  • OST science in grades 5 and 8
  • OST end of course, all subjects
