student_growth_norms_2015 NWEA student growth norms data (2015 study)

Description

Norm data published by NWEA: Given a subject, grade level, pre-test and post-test seasons and start RIT, expected growth and variance statistics.

Usage

student_growth_norms_2015

Format

Subject

Measurement Scale, Possible Values: 1=Mathematics, 2=Reading, 3=Language Usage, 4=General science

StartGrade

The RIT score of the first test in the a given period. Scores are now represented with as many as 14decimal places, which is clearly overboard.

T41

Growth projection for comparison period fall of this grade to winter of this grade. #' Negative numbers likely due to extrapolation.

T42

Growth projection for comparison period fall of this grade to spring of this grade. Negative numbers likely due to extrapolation.

T44

Growth projection for comparison period fall of this grade to fall of next grade. #' Negative numbers likely due to extrapolation.

T22

Growth projection for comparison period spring of this grade to spring of next grade. #' Negative numbers likely due to extrapolation.

T12

Growth projection for comparison period winter of this grade to spring of this grade. Negative numbers likely due to extrapolation.

T11

Growth projection for comparison period winter of this grade to winter of next grade. Negative numbers likely due to extrapolation.
