What standardized tests are used?

Each state administers its own standardized assessments for English Language Arts and Math, typically in grades 3-8. High school students may take the ACT, SAT, or a state-specific exam. Results are reported as the percentage of students meeting or exceeding grade-level expectations.

How should I interpret proficiency percentages?

Proficiency rates show the percentage of students meeting grade-level expectations. A 60% proficiency rate means 6 out of 10 students tested at or above grade level. Compare against state averages and similar districts for context, as raw numbers alone do not tell the full story.

What are accountability designations?

Under the Every Student Succeeds Act (ESSA), schools receive designations based on performance. 'Exemplary' schools perform well above average. 'Commendable' schools meet targets. Schools identified for 'Targeted' or 'Comprehensive' support need improvement in specific areas or overall performance.
