11.14 - Question Bank Blueprint and Coverage Matrix
Module: Standalone Reference Appendices and Instructor Resources
Purpose: Maintain a traceable blueprint for every assessment question in the course and verify coverage across Core, Type I, Type II, Type III, module learning outcomes, and current EPA Section 608 test-topic headings
Question-bank audit date: August 14, 2026
Repository audit basis: Current course snapshot generated August 14, 2026 at 21:18:30 America/New_York
Official test-topic taxonomy: Current U.S. EPA Section 608 Test Topics page, checked August 14, 2026
Current project readiness standard: At least 22/25 in Core, Type I, Type II, and Type III on two separate closed-book cumulative attempts, with no unresolvedP1errors
1. Purpose and Scope
This file serves four functions:
- Defines the metadata that must accompany every existing and future question.
- Audits the current question bank against the course structure and current EPA test-topic headings.
- Demonstrates assessment coverage of the course’s major instructional outcome clusters.
- Identifies coverage, answer-key, and governance gaps that should be corrected before a future release.
This is a question-bank control document, not a student practice set. The primary EPA category assigned to a course question is a project-maintenance classification. EPA publishes test-topic headings, but EPA does not classify or approve these project questions.
2. Current Question-Bank Audit Summary
The current repository contains 1,280 unique multiple-choice question instances in Modules 1-10.
| Audit Item | Current Result |
|---|---|
| Unique question IDs | 1,280 |
| Embedded concept-check questions | 620 |
| Module/Type practice questions | 400 |
| Cumulative review concept checks | 10 |
| Universal Mock Examination 1 | 100 |
| Universal Mock Examination 2 | 100 |
| Optional remediation examination | 50 |
| Questions with mapped answer letter | 1,280 / 1,280 |
| Major instructional subsections audited, Modules 1-9 | 75 / 75 assessed |
| Numbered learning objectives in those subsections | 666 |
| Embedded questions in those subsections | 620 |
2.1 Important Answer-Key Control Note
Of the 1,280 questions, 1,270 have an explicit corresponding answer block in an existing answer file. The 10 cumulative questions in 10.3 - Commonly Confused Terms.md state that their answers may be discussed or incorporated later, but the current snapshot does not contain a dedicated answer block for those 10 items.
For this audit, the intended answers were resolved directly from the course content and the answer choices:
| Question ID | Audit Answer |
|---|---|
10.3-1 | A |
10.3-2 | B |
10.3-3 | C |
10.3-4 | B |
10.3-5 | B |
10.3-6 | C |
10.3-7 | A |
10.3-8 | B |
10.3-9 | C |
10.3-10 | C |
Maintenance action: Before a final release, add an explicit answer section or answer-key cross-reference for these 10 questions so that the master register does not depend on an audit-derived answer.
3. Required Metadata for Every Question
Every new or revised question must have the following metadata in the master register.
| Field | Requirement |
|---|---|
| Question ID | Unique ID in the form subsection-question, such as 8.12-17 |
| Module | Module number and, when useful, module name |
| Subsection | Source instructional, practice, mock, or remediation subsection |
| Certification section | Core, Type I, Type II, or Type III |
| Official test-topic category | One primary current EPA heading from Section 5, or ADMIN when the item is course/provider administration rather than a listed EPA technical topic |
| Difficulty | B, S, A, or C using Section 6 |
| Question type | Primary cognitive/question format using Section 7 |
| Correct answer | One letter, A through D |
| Error category | One primary project error code using Section 8 |
| Regulatory verification date | Date on which the source question/answer bank was technically or regulatorily checked |
| Quiz or mock use | CC, P, CR, M1, M2, or R |
| Topic | Concise concept tested, normally taken from the detailed answer explanation |
3.1 Question ID Rule
Use:
SUBSECTION-QUESTION NUMBER
Examples:
5.11-24
8.13-7
10.8-51
Question IDs must remain stable after publication. If a question is materially replaced, preserve revision history instead of silently reusing an old ID for a different concept.
4. Quiz and Examination Use Codes
| Code | Use |
|---|---|
CC | Embedded concept check |
P | Module/Type practice |
CR | Cumulative review concept check |
M1 | Universal Mock 1 |
M2 | Universal Mock 2 |
R | Optional remediation |
A question may later be adapted for another use, but the adapted item should receive a new ID when wording, conditions, distractors, or answer logic changes materially.
5. Current EPA Test-Topic Taxonomy Used by This Blueprint
The current EPA Test Topics page organizes the certification content under Core and Types 1, 2, and 3. This project uses the equivalent project labels Type I, Type II, and Type III.
5.1 Core
| Code | EPA Heading |
|---|---|
C-EI | Environmental Impacts |
C-CAA | Clean Air Act and Montreal Protocol |
C-608 | Section 608 Regulations |
C-SUB | Substitute Refrigerants and oils |
C-REF | Refrigeration |
C-3R | Three R Definitions |
C-REC | Recovery Techniques |
C-EVAC | Dehydration Evacuation |
C-SAF | Safety |
C-SHIP | Shipping |
ADMIN | Course/provider readiness or assessment administration; not separately listed as an EPA technical test-topic heading |
5.2 Type I
| Code | EPA Heading |
|---|---|
I-RR | Recovery Requirements |
I-RT | Recovery Techniques |
I-SAF | Safety |
5.3 Type II
| Code | EPA Heading |
|---|---|
II-LD | Leak Detection |
II-LR | Leak repair requirements |
II-RT | Recovery Techniques |
II-RR | Recovery Requirements |
II-REF | Refrigeration |
II-SAF | Safety |
5.4 Type III
| Code | EPA Heading |
|---|---|
III-LD | Leak Detection |
III-LR | Leak repair requirements |
III-RT | Recovery Techniques |
III-RC | Recharging Techniques |
III-RR | Recovery Requirements |
III-REF | Refrigeration |
III-SAF | Safety |
5.5 Primary-Tag Rule
Many course questions integrate more than one concept. The master register records one primary EPA heading based on the concept required to select the best answer. Secondary concepts remain visible through the source subsection and Topic field.
Do not interpret the project tag as an EPA endorsement or as a claim that the official examination uses the same wording or weighting.
6. Difficulty Standard
| Code | Level | Working Definition |
|---|---|---|
B | Basic | Direct recall, identification, or a single definition with little competing context |
S | Standard | One-step distinction or application with plausible distractors |
A | Applied | Scenario, multi-condition rule, calculation/table use, or current-versus-historical discrimination |
C | Challenging | Integrated high-complexity item requiring several conditions or distinctions |
Existing questions that already carry an explicit difficulty tag retain that tag. Questions without an explicit tag are assigned an audit difficulty from their cognitive demand. Future question files should store difficulty explicitly rather than relying on later inference.
Current Difficulty Distribution
| Difficulty | Questions |
|---|---|
Basic (B) | 149 |
Standard (S) | 810 |
Applied (A) | 311 |
Challenging (C) | 10 |
7. Question-Type Standard
| Code | Primary Question Type |
|---|---|
DEFN | Definition/terminology |
CLASS | Classification |
RULE | Rule/threshold |
PROC | Procedure/sequence |
SAFE | Safety/hazard |
PT | P-T/pressure/vacuum |
CALC | Calculation/units |
HIST | Current-vs-historical |
SCEN-D | Scenario/distractor-reading |
SCEN | Scenario/application |
TECH | Technical concept |
Current Question-Type Distribution

10. Assessment-Target Reconciliation
The project outline contains two assessment-volume statements that are not fully consistent with one another. The earlier first-edition plan specifies 50 Type I, 75 Type II, and 75 Type III dedicated practice questions. A later project-wide minimum table lists 75, 100, and 100 respectively. The current repository follows the earlier dedicated-set design.
| Assessment Category | Current Distinct Instances | Earlier First-Edition Plan | Later Project-Wide Minimum | Audit Status |
|---|---|---|---|---|
| Embedded concept checks | 620 | Not separately fixed in the earlier table | 150 | Exceeds later minimum |
| Core module practice, Modules 1-6 | 200 | 190-220 area total was planned across Core/foundations | 200 | Meets later minimum exactly |
| Type I dedicated practice | 50 | 50 | 75 | Meets earlier plan; 25 below later minimum |
| Type II dedicated practice | 75 | 75 | 100 | Meets earlier plan; 25 below later minimum |
| Type III dedicated practice | 75 | 75 | 100 | Meets earlier plan; 25 below later minimum |
| Universal Mock 1 | 100 | 100 | 100 | Meets both |
| Universal Mock 2 | 100 | 100 | 100 | Meets both |
| Remediation examination | 50 | 50-100 | 50 | Meets both |
| Total current question instances | 1,280 | 540-620 before reuse/overlap | 975 | Exceeds aggregate minimum |
10.1 Module Readiness Quiz Target
The later outline separately lists a target of 100 module readiness quiz questions. The current repository does not contain a separately labeled 100-question readiness-quiz bank. The module practice files function as readiness assessments, but those same questions are already counted as module/Type practice questions.
Control rule: Do not double-count the same question merely to satisfy two blueprint rows. A future governance revision should either define
module readiness quizas an overlapping functional label or create a distinct question set.
10.2 Readiness-Target Reconciliation
An older project-outline line uses an 85 percent section target. The current operational readiness files use the newer standard:
22 / 25 OR HIGHER
IN CORE, TYPE I, TYPE II, AND TYPE III
ON TWO SEPARATE CLOSED-BOOK CUMULATIVE ATTEMPTS
WITH NO UNRESOLVED P1 ERRORS
Since 22/25 equals 88 percent, this file uses the 22/25 twice standard. The older 85 percent line should be updated during the next project-governance cleanup.
11. Current EPA Test-Topic Coverage Matrix
The following matrix counts each question once under its primary EPA test-topic tag.
| Section | Code | Current EPA Topic Heading | Questions | Status |

11.1 Identified EPA-Topic Gap
The current audit finds no Type III question whose primary tested concept is the EPA heading Leak repair requirements.
The course does assess:
- Type III leak direction and leak indicators.
- Low-pressure leak-test pressurization.
- Leak-inspection/chronic-leaker concepts under Type III leak detection.
- Current Section 608 leak-repair requirements elsewhere, especially in Core/Type II material.
However, those do not substitute for a Type III-specific question whose controlling answer is the applicable leak-repair requirement.
Recommended Correction
Add at least 3-5 original Type III questions explicitly testing the current leak-repair framework in a low-pressure-appliance context. The new items should cover, as applicable to the course scope:
- Applicability of the current Section 608 ODS leak-repair framework to a qualifying low-pressure appliance.
- The applicable annual leak-rate category for the stated use.
- The full-charge threshold and the condition that makes the rule apply.
- Repair/verification or related recordkeeping logic without confusing it with Type III leak-detection procedures.
- Separation of current Section 608 ODS requirements from the separate AIM Act HFC framework where relevant.
Do not copy or reconstruct secure certification questions. Any added items must be original and must be verified against current official sources before release.
12. Major Instructional Outcome Coverage Matrix
For this audit, a major learning outcome is treated as the learning-scope cluster of one normal instructional subsection in Modules 1-9. This is the appropriate level for proving course coverage because many numbered learning objectives intentionally support the same integrated concept-check question.
The repository contains 75 normal instructional subsections, 666 numbered learning-objective statements, and 620 embedded concept-check questions. Every one of the 75 instructional subsections has at least one direct embedded assessment; in fact, the current minimum is 8 concept-check questions per audited instructional subsection.
This does not claim a one-question-to-one-objective mapping for all 666 individual objective bullets. It proves that no major subsection-level instructional outcome cluster is left without direct assessment.

12.1 Outcome-Coverage Conclusion
At the major instructional subsection level, the current course has direct assessment coverage for 75 of 75 outcome clusters.
The separate EPA-topic audit in Section 11 is more stringent and identifies one distribution gap: Type III Leak repair requirements lacks a Type III-primary-tagged item. This should be corrected even though leak-repair concepts are taught and assessed elsewhere in the course.
13. Blueprint for Future Question Development
13.1 Minimum Rules for a New Question
Before a question is merged:
- It must test content already taught or explicitly designated for the same assessment.
- It must have four choices, A-D, with one best answer.
- Distractors must be plausible and diagnosable.
- The answer must be traceable to the course and, when rule-dependent, to a current authoritative source.
- A numerical answer must include units and the condition that controls the number.
- Current and historical regulatory values must not be mixed without explicit labeling.
- The question must receive all metadata required in Section 3.
- The question must be checked for near-duplication against the bank in this file.
- The question must not reproduce, paraphrase too closely, or solicit recalled secure certification-test content.
13.2 Recommended Cognitive Mix
A balanced new set should include a deliberate mixture of:
- Direct definitions/recognition.
- Classification.
- Rule/threshold with conditions.
- Procedure or sequence.
- Safety/hazard recognition.
- P-T, pressure, vacuum, or units where relevant.
- Scenario/application.
- Current-versus-historical discrimination where the topic is vulnerable to obsolete study material.
13.3 Mock Examination Rule
Universal mocks should remain substantially independent. Do not populate Mock 2 by simply copying Mock 1 with reordered choices. Reusing the same concept is acceptable when the appliance, conditions, distractor logic, or required reasoning are meaningfully different.

15. Question-Bank Maintenance Procedure
When adding, revising, moving, or retiring a question:
- Confirm the source subsection and unique question ID.
- Confirm Core, Type I, Type II, or Type III assignment.
- Assign one primary current EPA test-topic category.
- Assign difficulty and question type.
- Confirm one correct A-D answer.
- Assign a primary error category.
- Verify all rule-dependent content against current authoritative sources.
- Record the verification date.
- Assign the intended quiz/mock use.
- Update the section-level and EPA-topic coverage counts.
- Check for duplicate or near-duplicate questions, especially across the two Universal mocks.
- Update the corresponding answer file and explanations.
- Recheck that every distractor has a defensible reason for being wrong.
- If a current regulation changes, use
11.15 - Regulatory Verification and Update Procedure.mdto identify every affected question.
16. Release QA Checklist
