The Pandemic Recovery report compares how overall achievement on the state assessments in 2021-22 has changed from 2018-19. The horizontal line (x-axis) shows 2018-19 achievement. The vertical line (y-axis) shows the difference in achievement from 2018-19 to 2021-22. If the difference in achievement from 2018-19 to 2021-22 is greater than zero (see horizontal line at 0), then achievement exceeds pre-pandemic levels. If the difference is less than zero, then achievement lags pre-pandemic levels.
The measure used is the Performance Index (see brief video explanation of the index). This is the average achievement from all state academic assessments – standard and alternate assessments – in the three tested subjects of English language arts (ELA), mathematics, and science. It ranges from 0 to 100. The state target for the Performance Index is 75. This is reflected by the vertical line (called Target) at 75. An index of 75 means that students, on average, are performing solidly in the desired achievement level on their respective assessment.
