Evidence, correction, retake, mastery
Geometry Assessment Center
Every graded progression gate requires at least 80% mastery. Browser-local results are learning and evaluator evidence; official credit is determined from the retained evidence record.
Course-wide evidence
Readiness and cumulative assessments
40-Question Diagnostic
Non-gating Algebra I, proportion, coordinate, measurement, and reasoning readiness evidence.
36 Weekly Mastery Gates
10 questions per week · 360 unique prompts · 8/10 required · five depth dimensions represented every week.
Midterm · Mixed Evidence
60 selected-response questions across Units 01–06 plus 6 required human-reviewed constructed responses. All three 80% thresholds must be met.
Final · Mixed Evidence
100 selected-response questions across Units 01–13 plus 10 required human-reviewed constructed responses. All three 80% thresholds must be met.
Administration Guide
Mastery rules, evidence sequence, constructed-response rubric, accommodations, corrections, integrity, privacy, and record status.
Completion Record
Locks until all 90 lesson gates, 36 weekly gates, 13 unit checks, both cumulative exams, 13 investigations, and the capstone/defense evidence are complete.
Formal unit evidence
13 cumulative 20-question mastery checks
Each unit check represents every instructional week in the unit and balances procedural fluency, multi-step application, representation/interpretation, error analysis, and transfer reasoning. All unit lesson and weekly gates must already be mastered before the check opens.
