Geometry Assessment Administration Guide
This guide describes the evidence required by the course runtime and the responsibilities of the parent, teacher, school, or authorized evaluator who determines official credit.
1. Mastery contract
80% is the minimum mastery threshold at every graded progression gate. A below-80 attempt may be retained as learning evidence and should trigger review, correction, and retesting, but corrections alone do not unlock the next graded stage.
- 90 lesson evidence gates: evaluator score of at least 80% on the completed lesson/worksheet evidence.
- 36 weekly mastery gates: 10 questions each; at least 8/10 required.
- 13 formal unit mastery checks: 20 questions each; at least 80% required.
- Midterm and Final: selected response, human-reviewed constructed response, and weighted overall score must each reach at least 80%.
- Course completion additionally requires all 13 applied investigations, an evaluated capstone/defense score of at least 80%, evaluator attestation, learner/evaluator identification, and a completion date.
2. Evidence sequence
- Teach and complete the assigned lesson. Retain written work, constructions, diagrams, calculations, CAD output, or other required evidence.
- The evaluator reviews the completed lesson evidence and records a 0–100 lesson mastery score. A score below 80 requires correction and retake/re-evaluation before progression.
- At each week boundary, complete the fixed 10-question weekly mastery set. The weekly bank measures procedural fluency, multi-step application, representation/interpretation, error analysis, and transfer reasoning.
- After every lesson and weekly gate assigned to a unit is mastered, complete the 20-question formal unit mastery check. The unit blueprint represents every instructional week and allocates four questions to each of the five depth dimensions.
- Complete the reviewed Midterm after Units 01–06 and Weeks 01–18. Unit 07 remains locked until Midterm mastery is complete.
- Complete the reviewed Final only after all 13 unit checks, all 36 weekly gates, and Midterm mastery are complete.
- Issue a completion record only after the full lesson, week, unit, cumulative-exam, investigation, and capstone evidence chain is satisfied and the learner, evaluator, and completion date are recorded.
3. Weekly and unit assessment depth
The 36 weekly assessments contain 360 unique prompts. Each week uses two questions in each of five dimensions: procedural fluency, multi-step application, representation/interpretation, error analysis, and transfer reasoning.
Formal unit mastery uses a deterministic 20-question cumulative blueprint derived from the week-aligned depth bank for that unit. Every instructional week in the unit must be represented, with four questions from each depth dimension. The unit source fails closed if the required depth bank does not load completely.
Important: these are public, browser-delivered mastery checks. They are appropriate for course progression and formative/summative evidence in a family or school evaluation process, but they are not confidential secure-testing instruments. For higher-stakes credit decisions, pair them with retained written work, projects, oral explanation, and evaluator observation.
4. Midterm and Final mixed evidence
The cumulative exams intentionally require both recognition/selection and produced mathematical reasoning.
- Midterm: 60 selected-response questions across Units 01–06 plus 6 required constructed-response tasks.
- Final: 100 selected-response questions across Units 01–13 plus 10 required constructed-response tasks.
- Weighting: selected response 70%; constructed response 30%.
- Full mastery: selected-response score ≥80%, constructed-response score ≥80%, and weighted overall score ≥80%.
The browser scores selected response. A parent, teacher, or authorized evaluator scores each constructed response from 0–4 using the displayed rubric. Until that review is complete, cumulative mastery remains pending.
5. Constructed-response rubric
- 4: complete and correct geometric reasoning; relevant representation, theorem/formula, units, verification, interpretation, and limitations are explicit.
- 3: substantially correct reasoning with a minor omission or small non-conceptual error.
- 2: partial reasoning with meaningful understanding but a conceptual gap, incomplete verification, or weak interpretation.
- 1: limited relevant work with major misconceptions or unsupported conclusions.
- 0: blank, unrelated, or no assessable geometric reasoning.
6. Administration conditions
- Provide quiet time, scratch paper, graph paper, construction tools, and approved reference materials appropriate to the task.
- Allow documented accommodations without lowering the mathematical mastery threshold.
- Use a calculator, dynamic geometry environment, or CAD only when the lesson or assessment permits it.
- Require diagrams, units, theorem/formula justification, and verification when the prompt calls for them.
- Do not award mastery from visual appearance alone when geometric proof or measurement evidence is required.
- Retain representative written work or exported evidence with the learner record.
7. Corrections and retesting
For a below-mastery attempt, have the learner identify the error, show the corrected method, explain why the correction works, and identify the transferable lesson. Then administer a new attempt or re-evaluate the required evidence. The historical attempt remains useful evidence; progression remains locked until an actual mastery score reaches 80%.
8. Integrity, privacy, and record status
Geometry records are stored in the local browser. They are editable, are not cryptographically signed, and are not independently verified by a server. The software therefore treats them as browser-local evidence, not as a self-authenticating transcript or credential.
The named parent, teacher, school, or authorized evaluator remains responsible for determining official credit from retained evidence. Do not place confidential student information into exports or shared devices unless the evaluator has an appropriate privacy process.
9. Recommended completion record
Retain enough evidence to reconstruct the learner's work: lesson and worksheet samples, weekly and unit results, cumulative-exam reports and written responses, applied investigations, CAD or construction artifacts where relevant, capstone/defense evidence, learner name, evaluator name, and completion date. The printable completion record remains locked until those identifying fields and the full evidence chain are present.
Course completion is evidence-gated. A dashboard percentage, manually edited browser storage, or a printed page by itself does not establish official Geometry credit.
