How this district's change over time is ranked
TEA publishes most measures for one year only, so a change ranking exists just where the same figure is published across years — the overall score, the five score domains, and per-student spending. This page does not yet state where Lancaster ISD itself places on these lists, only that the lists exist; open one to find this district's own row.

Where the score comes from
Texas builds the overall rating from the better of Student Achievement and School Progress, weighted 70%, plus Closing the Gaps at 30%. School Progress is itself the better of Academic Growth and Relative Performance. The 60, 70, 80 and 90 rules mark the letter-grade thresholds.

| Domain | Score | Grade | Points to next grade |
|---|---|---|---|
| Student Achievement | 75 | C | 5 |
| School Progress | 81 | B | 9 |
| Closing the Gaps | 79 | C | 1 |
| Academic Growth | 74 | C | 6 |
| Relative Performance | 81 | B | 9 |
Closest to moving up: Closing the Gaps, 1 point below B in that domain — the nearest of the measures that count toward the overall rating.
TEA does not add the domains up. The overall score is the better of Student Achievement and School Progress at 70%, plus Closing the Gaps at 30%. For this district that better measure is School Progress (81), so Student Achievement (75) is published above but does not enter the overall score at all — gaining points there changes nothing until it passes 81.

These are selected high placements, not a summary. Every figure above this section is the full picture, including where this district ranks poorly. Each statement below states its cohort and its denominator so it can be checked — a rank without an n is a boast, not a fact. Ties are shown because a shared ceiling is not a sole first place. Every ranking this site publishes, including the ones no district would put in a press release.
