Module F9-ET-02: Assessment Design Principles
Learning Objective
By the end of this module, you can apply constructive alignment to verify whether an assessment task genuinely measures a stated learning objective, classify assessment items by cognitive demand level, and rewrite a vague grading criterion into one that produces consistent judgements without requiring interpretation.
1. Constructive Alignment
Assessment does not exist in isolation. It exists in a chain with two other elements: the learning objective (what the learner is supposed to be able to do) and the instructional activity (what the learner has done to build that capacity). When these three elements cohere, assessment is constructively aligned.
The term was introduced by John Biggs to name the most common structural failure in educational design: misalignment between what is stated as the goal and what is actually tested. A course might state that learners will "critically evaluate competing explanations" but assess them with a question asking them to "describe three explanations". Description does not require evaluation. The learner can pass by recalling without critiquing. The credential thus produced does not support the stated claim.
Constructive alignment requires that:
- The learning objective names a specific cognitive act, not a general topic area ("evaluate the strengths and limitations of X" rather than "understand X").
- The instructional activity develops the named cognitive act, not only the background knowledge it operates on (the learner practises evaluation, not only reads about X).
- The assessment task elicits the named cognitive act, not a proxy for it.
The third condition is the one most frequently violated. Common violations:
| Objective states | Assessment tests | Failure mode |
|---|---|---|
| Evaluate arguments | Reproduce arguments | Substitution (recall instead of evaluation) |
| Apply a model to a novel case | Apply a model to a case practised in class | Mimicry (pattern-matching instead of transfer) |
| Construct an explanation | Select the best explanation from four options | Proxy (recognition instead of production) |
A multiple-choice question can test evaluation, but only if the options force the learner to discriminate between arguments on principled grounds, not to recognise a memorised answer. The format is not the failure; the mismatch between demanded and elicited cognitive act is the failure.
2. Formative and Summative Assessment
Formative assessment is assessment whose primary purpose is to give the learner (and the tutor) information that can change what happens next. It occurs during learning. Its value lies entirely in the feedback loop it creates: the learner discovers what they understand, what they misunderstand, and what to do about it.
Summative assessment is assessment whose primary purpose is to represent the learner's competence at a defined moment. It occurs at or near the end of a learning period. Its value lies in the credential it produces — a defensible claim about what the learner can do.
These are not opposites. The same task can serve both functions. But the design constraints differ:
| Dimension | Formative | Summative |
|---|---|---|
| Timing | During learning | End of learning period |
| Feedback depth | Diagnostic and actionable | Evaluative and recorded |
| Stakes | Low — errors are expected and productive | High — represents final competence claim |
| Frequency | High — multiple opportunities | Low — one or few occurrences |
| Grading precision | May be qualitative or impressionistic | Must be defensible and consistent |
An agent acting as tutor interacts primarily in the formative register. Feedback given during a lesson is formative: it should tell the learner what they got right, why a wrong answer was wrong, and what to try next. This feedback serves learning in progress, not a record that will follow the learner.
An agent acting as assessor or co-evaluator interacts in the summative register. The stakes are higher and the grading criteria must be robust: a different evaluator applying the same criteria to the same response should reach the same judgement.
The design error most common in formative assessment is insufficient feedback depth: a correct/incorrect signal without explanation does not close the learning gap. The design error most common in summative assessment is insufficient rubric precision: criteria that require interpretation produce inconsistent grades, undermining the credential function.
3. Cognitive Demand and Bloom's Taxonomy
Bloom's Taxonomy (revised by Anderson and Krathwohl) classifies cognitive acts into six levels of increasing demand:
| Level | Act | Example verbs |
|---|---|---|
| 1 — Remember | Retrieve from memory | Define, list, recall, state |
| 2 — Understand | Construct meaning | Explain, paraphrase, classify, summarise |
| 3 — Apply | Use in a given context | Solve, execute, use, implement |
| 4 — Analyse | Break into components and examine relationships | Compare, distinguish, infer, attribute |
| 5 — Evaluate | Make judgements using criteria | Assess, critique, justify, defend |
| 6 — Create | Produce something new | Design, construct, generate, plan |
The taxonomy is useful not as a strict hierarchy — real learning tasks often span levels — but as a diagnostic tool for misalignment. When an objective verb is at level 4 (analyse) and an assessment item elicits level 2 behaviour (summarise), the mismatch is visible and correctable.
For agent tutors, the taxonomy is useful at two points: when checking whether a question you have been asked to evaluate actually tests what the requester thinks it tests, and when designing or critiquing a practice task for a learner.
The most common mistake is writing objectives at a high level but constructing tasks that are answerable at a low level because low-level tasks are easier to grade. This is the rubric precision trap: difficult judgements get avoided by asking simpler questions, but the simpler questions do not test what the course claims.
4. Deterministic Grading Criteria
A grading criterion is deterministic if two independent evaluators applying it to the same response reach the same conclusion without discussion. Deterministic criteria share three properties:
- Specificity: the criterion names what must be present (or absent), not a quality to be assessed. "Identifies the correct formula" is deterministic. "Demonstrates mathematical understanding" is not.
- Completeness: the criterion covers all conditions necessary for the grade. A response that satisfies every stated criterion and is awarded the grade should not surprise any informed reader.
- Independence: each criterion can be evaluated without reference to the evaluator's overall impression of the response. Holistic criteria ("overall quality of reasoning") require interpretation; atomised criteria ("names at least two counterarguments and states a reason why each fails") do not.
Writing deterministic criteria is a skill, not a formula. The process:
- Identify the cognitive act being tested (e.g. evaluate an argument).
- List the visible indicators of competent performance (e.g. identifies the main claim, names a relevant objection, explains why the objection does or does not undermine the claim).
- State each indicator as a binary (present / absent) or quantified (names at least two / fewer than two) condition.
- Test the criteria on borderline responses. If two evaluators disagree about whether a criterion is met, the criterion is not yet deterministic.
The test in step 4 is the one most frequently skipped under time pressure. Criteria that seem clear in the abstract become ambiguous when applied to a real response that partially satisfies them. An agent producing grading criteria for use in a live assessment context should apply this test before the criteria are deployed.
Practice Tasks
The following deterministic tasks have grading criteria that can be evaluated without additional reference. Complete each before reviewing the answer key.
F9-ET-02-1: Identify an alignment failure
A module for trainee accountants states this learning objective: "Evaluate the appropriateness of different depreciation methods for a given asset type and business context."
The end-of-module assessment asks: "Name three common depreciation methods and state the main advantage of each."
Identify: (a) Which level of Bloom's Taxonomy does the learning objective operate at? (b) Which level does the assessment task operate at? (c) Describe the specific alignment failure and state what the assessment actually measures instead.
Grading criteria: (a) must identify level 5 (Evaluate) — the objective requires making a judgement about appropriateness, not recalling or explaining. (b) must identify level 1 or 2 (Remember or Understand) — naming and stating advantages requires recall and basic explanation. (c) must describe the mismatch as substitution: the assessment tests recall and comprehension of depreciation methods, not the evaluative capacity to select the appropriate method for a context. A correct (c) notes that a learner could pass the assessment by memorising without being able to evaluate, which is what the objective claims to certify.
F9-ET-02-2: Classify by cognitive demand
Classify each of the following assessment items by Bloom's Taxonomy level. Give the level name and the level number for each.
A. "Define the term 'opportunity cost'." B. "A city is considering building a new stadium. It has three possible sites. Using opportunity cost reasoning, recommend which site minimises cost to the public and justify your recommendation." C. "Explain the difference between opportunity cost and sunk cost." D. "You have been given the following decision matrix. Identify which alternative has the lowest opportunity cost and explain why the others have higher costs."
Grading criteria: Acceptable answers: A = Remember (1); B = Evaluate or Create (5 or 6) — the item requires applying the concept, weighing alternatives, and defending a recommendation; either level is acceptable with appropriate justification. C = Understand (2) — contrasting two concepts requires constructing meaning and recognising a distinction, not applying or evaluating. D = Analyse (4) — the item requires examining a matrix, breaking down the alternatives, and inferring their relative costs. A response that places B at Apply (3) must explain the reasoning; it is acceptable only if the justification notes that the item could be completed by mechanical application without genuine evaluation. A response that places D at Apply (3) should note the distinction between applying a formula and analysing relationships; Apply is acceptable if justified.
F9-ET-02-3: Rewrite a vague rubric criterion
The following rubric criterion is in use for a university-level essay assignment:
"The response demonstrates good understanding of the theoretical framework and applies it appropriately."
Rewrite this as two deterministic criteria that two independent evaluators could apply to the same essay and reach the same conclusion without discussion.
Grading criteria: A passing rewrite must produce exactly two criteria (not one combined criterion, not three). Each must be independently evaluable. Each must be binary (present / absent) or quantified. A passing criterion for "understanding" might read: "The response names the core claim of the theoretical framework without error and distinguishes it from at least one related framework." A passing criterion for "appropriate application" might read: "The response applies the framework to the case study by mapping at least two framework concepts to specific features of the case, and does not attribute to the framework a claim the framework does not make." The key test: could a marker evaluating only that criterion, in isolation, reach a yes/no decision without invoking overall impressions? If yes, the criterion passes. A rewrite that retains the word "appropriately" or "good" without specifying what appropriate or good means fails — it defers the interpretive problem rather than solving it.
Reflective Task
F9-ET-02-R: Design an aligned assessment
You are supporting the design of a short module for AI practitioners on the topic of prompt injection attacks. The stated learning objective is:
"Identify structural features in a prompt that suggest an injection attempt has occurred, and distinguish these from features that are present in legitimate prompts."
Design a single summative assessment task that:
- Is constructively aligned with this objective (the task directly elicits the stated cognitive act).
- Operates at the appropriate Bloom's level.
- Can be graded with deterministic criteria.
Your answer must include:
- The assessment task (written as it would be presented to the learner, ≤100 words).
- The Bloom's level and a justification.
- At least three deterministic grading criteria.
- A statement of one alignment risk in your design — a way in which a learner could satisfy the criteria without actually meeting the objective — and how you would close it.
Minimum length: 250 words. Maximum: 500 words.
Scoring dimensions (for human reviewer):
- Alignment: the assessment task elicits the stated act (identification and discrimination) without substituting recall, explanation, or a lower-demand proxy: (0–2)
- Bloom level accuracy: correctly identified with a defensible justification: (0–1)
- Determinism: each criterion is evaluable by two independent markers without discussion: (0–2)
- Honest risk statement: names a specific way the criteria could be gamed or passed without meeting the objective, and closes the gap: (0–2)
- Total: 7 points
Canonical answers for deterministic tasks and scoring guidance for reflective tasks are in the answer key for this module. Answer keys are reviewer-only.
