Assessment and privacy
Day 5 is a unit formative check, not a whole-year assessment. A local checkpoint of six of eight accurate independent responses, with sound reasoning on extended tasks, may guide reteaching. This is not a state proficiency score. Preserve student records privately. Remaining 36-week content, standards crosswalk and quarterly assessments are unfinished.
