10.15 - Official Examination Readiness Checklist

Module: Universal Review and Mock Examinations
Purpose: Final go/no-go checklist before scheduling and taking the official EPA Section 608 Universal certification examination
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 unresolved P1 errors
Provider-information review basis: Current project information verified August 14, 2026
Important: EPA requirements and certifying-provider procedures are different. Confirm the selected provider’s current instructions immediately before the official examination.

How to Use This Checklist

Complete this file after:

1. Finishing the Module 10 review sheets.
2. Completing Universal Mock Examination 1.
3. Correcting all Mock 1 errors through Section 10.10.
4. Completing Universal Mock Examination 2.
5. Correcting remaining errors.
6. Completing targeted remediation from Section 10.13 when needed.

Do not mark an item complete because it was reviewed once.

Mark it complete only when the requirement has actually been satisfied.

Use:

[ ] = NOT YET CONFIRMED
[x] = CONFIRMED

The official Universal examination should be scheduled only when all hard-stop readiness items are complete.

Part 1 - Universal Knowledge Readiness

1.1 Mock Examination Scores

Record the results from the two independent Universal mock examinations.

Required Project Target

22 / 25 OR HIGHER
IN EACH SECTION
ON BOTH MOCK EXAMINATIONS

• Core reached at least 22/25 on both independent mock examinations.
• Type I reached at least 22/25 on both independent mock examinations.
• Type II reached at least 22/25 on both independent mock examinations.
• Type III reached at least 22/25 on both independent mock examinations.
• Both mocks were completed closed book.
• Both mocks were completed without internet searching or outside assistance.
• The two mocks were taken as independent attempts rather than immediately after memorizing the answer files.
• Timing was realistic for the selected provider’s current Universal examination format.

Hard stop: A high total score does not compensate for a weak section. If any section remains below the project target, continue remediation before taking the official Universal examination.

1.2 Error-Log Closure

Use 10.10 - Error Analysis and Remediation.md.

• Every incorrect Mock 1 question was reviewed.
• Every incorrect Mock 2 question was reviewed.
• Every guessed or low-confidence answer was reviewed even when the selected answer happened to be correct.
• Every error has a known cause.
• Every P1 safety or regulatory error has been corrected.
• There are zero unresolved P1 errors.
• Repeated P2 errors have been corrected and retested.
• No unresolved error remains because of an outdated or legacy rule.
• No unresolved error remains because of confusion among pressure units.
• No unresolved error remains because of mixing Type I, Type II, and Type III rules.
• No unresolved error remains because of mixing Section 608 and Section 609 requirements.
• The learner can explain the corrected rule or principle without looking at the answer key.

Open-Error Summary

For official-exam readiness:

OPEN P1 ERRORS = 0

1.3 Remediation Completion

If Section 10.13 was needed:

• Weak topics were selected from the actual error log rather than chosen randomly.
• New remediation questions were answered closed book.
• Missed remediation questions were corrected.
• The weak concept was retested with a fresh question.
• The topic was closed only after the learner could state the controlling rule or physical reason without notes.

If Section 10.13 was not needed:

• Mock 1 and Mock 2 already demonstrated the project readiness standard in all four sections.

• I can distinguish a refrigerant monitor from an oxygen monitor.
• I know that a machinery room is not automatically an OSHA confined space.

Part 3 - High-Priority Numerical Verification

The following values are especially vulnerable to confusion.

Do not merely recognize the number. Be able to state:

NUMBER
+
CONCEPT
+
CONDITION
+
UNIT

3.1 Charge and Classification Values

• 5 lb or less — only one part of the complete small-appliance definition.
• Greater than 15 lb full charge — ordinary system-dependent recovery equipment restriction unless the permanent pump-out exception applies.
• 50 lb or more — current Section 608 ODS leak-repair applicability threshold for qualifying appliances.
• 200 lb — charge boundary affecting several Type II evacuation-table rows.
• 45 / 170 / 355 psia at 104°F — refrigerant pressure-classification boundaries / criterion.

3.2 Type I Values

• 80% — correct Type I recovery requirement under the applicable conditions.
• 90% — post-November 15, 1993 recovery equipment with a functional appliance compressor.
• 4 in. Hg vacuum — Type I alternative endpoint.
• November 15, 1993 — recovery/recycling-equipment date boundary.

3.3 Type II and Type III Evacuation Values

For recovery equipment manufactured on or after November 15, 1993:

• Very-high-pressure appliance → 0 in. Hg vacuum.
• High-pressure appliance under 200 lb → 0 in. Hg vacuum.
• High-pressure appliance 200 lb or more → 10 in. Hg vacuum.
• Medium-pressure appliance under 200 lb → 10 in. Hg vacuum.
• Medium-pressure appliance 200 lb or more → 15 in. Hg vacuum.
• Low-pressure appliance → 25 mm Hg absolute.

For pre-November 15, 1993 recovery equipment:

• I have reviewed the applicable 0 / 4 / 25 mm Hg absolute requirements in the current Table 1.

3.4 Current Section 608 ODS Leak-Repair Values

• Industrial process refrigeration → 30%.
• Commercial refrigeration → 20%.
• Comfort cooling → 10%.
• Other qualifying appliances → 10%.
• I will not substitute historical 35% / 15% values when a question asks for the current rule.

3.5 Major Repair and Special Pressure Values

• More than 4 in² of flow area open for more than 15 minutes is part of the major-repair definition.
• Qualifying non-major / leaking-section pressure concept → no higher than 0 psig when all regulatory conditions are satisfied.
• Current special oil-change opening provision → no higher than 5 psig.

3.6 Type III Examination-Preparation Values

These must remain separated from universal equipment-design ratings.

• 10 psig — low-pressure leak-test examination maximum used in this course.
• 10 psig — traditional low-pressure recovery-unit high-pressure cutout examination value.
• 15 psig — traditional low-pressure recovery-vessel rupture-disc examination value.
• 130°F — traditional Type III oil-heating examination value.
• 25 mm Hg absolute — current normal low-pressure Table 1 endpoint.

Hard stop: If any value above is being recalled without its condition or unit, review 10.2 - High-Priority Numbers and Thresholds.md before the official examination.

Part 4 - Approved Certifying Organization

4.1 Provider Approval

• I selected an EPA-approved Section 608 certifying organization.
• I confirmed the organization on EPA’s current approved-program list.

Provider Rule Record

5.2 SkillCat Example - Use Only If SkillCat Is the Selected Provider

Current public information from SkillCat lists:

Universal
→ 100 questions
→ 25 Core + 25 Type I + 25 Type II + 25 Type III
→ 2 hours
→ closed book
→ proctored

The same source also lists:

4 attempts

and:

approximately 4-hour wait between attempts

with a published typical proctor-review period of approximately:

1–2 days

However, provider policies can change.

In addition, current public materials from SkillCat use inconsistent wording about the passing-score method.

Therefore, if SkillCat is selected:

• I opened the current SkillCat examination instructions.
• I confirmed the current Universal time limit.
• I confirmed the current attempt limit.
• I confirmed the current retake wait.
• I confirmed the current proctoring rules.
• I confirmed the current passing / section-credit method inside the current SkillCat system.
• I will follow the current in-app examination agreement rather than an older public description.

The values above are provider-specific information, not permanent EPA regulatory requirements.

Part 6 - Identification and Account Preparation

• My name in the testing account matches the identification I will use.
• I have the type of identification required by the provider.
• The identification is current and readable.
• The provider has accepted any required identity-verification step.
• I know the login email / username for the testing account.
• I know the password or have verified account access.
• Multi-factor authentication, if required, has been tested.
• I will not wait until the scheduled examination time to discover an account-access problem.

Part 9 - Closed-Book Conduct

Unless the provider explicitly allows an item, assume it is not allowed.

During the secure Universal examination:

• I will not use notes or study guides.
• I will not search the internet.
• I will not message another person.
• I will not receive assistance.
• I will not photograph or record examination questions.
• I will not copy secure questions for later distribution.
• I will not use another device.
• I will follow the provider’s rules for leaving the testing area.
• I understand that violating examination-security rules can invalidate the attempt.

Part 10 - Examination Scheduling and Retake Buffer

Do not schedule the first official attempt so close to an employment, graduation, course, or other deadline that one technical problem or one failed attempt eliminates the possibility of a retake.

10.1 Scheduling Record

Official certification needed by: ____________________________

Planned first examination date: _____________________________

Planned first examination time: _____________________________

Current provider retake waiting period: ______________________

Current expected result / proctor-review time: _______________

Latest practical retake date: _______________________________

Scheduling Checklist

• The first examination is scheduled early enough to allow at least one retake if needed.
• The schedule includes the provider’s current retake waiting period.
• The schedule includes any provider review / approval time before a result becomes final.
• The schedule includes time for focused remediation if the first attempt is unsuccessful.
• The schedule does not depend on receiving an immediate result when the provider states review may take longer.
• I have not scheduled the examination immediately after an exhausting workday, overnight shift, or other condition likely to impair performance.

There is no project-wide fixed number of days that is correct for every provider and every deadline. Build the schedule from the current provider retake and review rules plus a reasonable remediation buffer.

Part 11 - Digital Credential and Certification Record

Before testing, know what will happen after a successful result.

• I know whether the provider issues a digital certificate, digital card, physical card, or combination.
• I know where the credential will appear.
• I know whether a provider review must finish before the credential is issued.
• I know whether a physical card requires a separate request or fee.
• I know how to contact the provider if the credential does not appear.
• I will save the certificate number immediately after certification.
• I will save the digital certificate in more than one secure location.
• I will record the issuing certifying organization.
• I will record the examination / certification date.
• I will provide a copy to an employer or school if required.

• I will not stay up excessively late attempting to study every detail again.

Part 13 - Exam-Day Final Check

Immediately before beginning:

• Correct date and start time confirmed.
• Correct provider account opened.
• Identification ready.
• Device connected to power.
• Internet stable.
• Camera working.
• Microphone working.
• Notifications disabled.
• Unauthorized applications closed.

Reading Strategy

For every question:

READ THE ENTIRE STEM
→ IDENTIFY THE SECTION / APPLIANCE
→ FIND THE CONTROLLING CONDITION
→ CHECK THE UNIT
→ WATCH FOR NOT / EXCEPT / FIRST / MAXIMUM / MINIMUM
→ ELIMINATE DISTRACTORS
→ SELECT ONE BEST ANSWER

Do not change an answer merely because of nervousness.

Change it when a specific technical, regulatory, numerical, or reading reason shows the original choice was incorrect.

Part 14 - Final Go / No-Go Decision

HARD-STOP ITEMS

Every item below must be YES.

Decision

ALL HARD-STOP ITEMS = YES
→ READY TO TAKE THE OFFICIAL UNIVERSAL EXAMINATION

ANY HARD-STOP ITEM = NO
