StartGrade

The RIT score of the test in the first term of the comparison period. Scores are now represented with as many as 14-decimal 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
