No state assessments at this grade
Students take their next one in Grade 4.
PSSA Science (Grade 4)
PSSA Science is the grade 4 spring science test, aligned to PA Standards (transitioning to STEELS).
- When given:
- spring
- Frequency:
- annual
NAEP (National Assessment of Educational Progress)
Federally administered sample-based assessment in reading, mathematics, science, and writing. NAEP results inform state-by-state comparisons rather than individual student or school accountability.
- When given:
- biennial in winter
- Frequency:
- every two years
