CVA Cheat Sheet 2026: One-Page Review of Must-Know Facts

Which CVA This Cheat Sheet Covers

"CVA" is a crowded acronym, and a surprising number of candidates study the wrong material because of it. This page covers one credential only: the Vibration Institute (VI) Certified Vibration Analyst Category I. It is not Mobius VCAT-I, not another issuer's Category I vibration certification, and not a valuation credential that happens to share the letters. If you need background on the name itself, see What Does CVA Stand For? and What Is CVA Certification?.

Treat everything below as a one-page memory aid. For depth on any single topic, each section links to a longer guide on this site, and the CVA Exam Prep practice tests let you convert these facts into recall under time pressure.

The Fast-Facts Table

Eligibility and Application Rules

You must clear two hurdles before you may sit the exam: 30 hours of qualifying training and six months of relevant experience. Training does not have to come from VI. Courses from other organizations may qualify, though you will need documentary evidence either way. The CF009 application (Application for Examination and Certification of Vibration Analysts, Revision 16, dated August 18, 2020, in its currently linked form) also requires employer or professional-associate verification of your experience. Formal education information on the form is optional.

Fees at a Glance

Budget in layers, because the exam fee is only one part of the cost:

• Exam: USD360 for the current U.S. initial examination.
• Retest: USD150 for the first retest if taken within 12 months of the initial exam. After that, retests cost the regular exam fee.
• Optional course: Introduction to Machinery Vibration (IMV) costs USD2,125 for members or USD2,225 for nonmembers, with the USD360 exam additional.
• Renewal: USD100 (U.S.) or USD150 (international) by points; USD275 posted for U.S. Category I renewal by examination.

The twelve-month retest window is the one fee fact candidates most often forget. If a first attempt falls short, scheduling the retest promptly keeps the lower price. The CVA certification cost breakdown adds the surrounding expenses such as travel and calculators.

Exam Format: What Is Verified and What Is Historical

This is the section where precision matters most. The most recent handbook available to us for review is the Certification Handbook for Vibration Analyst Categories I-IV, Revision 10, December 13, 2022. It describes:

• 63 multiple-choice questions in two hours
• 60 scored questions plus three unmarked beta questions
• Calculations and interpretation of plots, tables and charts
• Closed-book testing with supplied equations

A newer handbook, the 2025 edition linked from VI navigation, could not be retrieved, so its revision number and contents are not assumed here. That makes the 63-question figure a historical handbook detail, not a confirmed current count. Separately, the current IMV course page describes a typical two-hour Category I examination held outside the course agenda, subject to scheduling changes.

How the Scoring Works

The handbook uses exam-specific psychometric (Angoff-style) cut scores rather than a single universal percentage. There is no fixed "70% to pass" rule for this credential, and a number borrowed from another certification should not guide your preparation. Aim for broad mastery instead of a target percentage. Our CVA passing score article and pass rate analysis explain what can and cannot be said about results.

Where and How You Test

VI-approved proctors administer examinations at VI's office, after courses, in approved private sessions and through international representatives. VI's reference-equation resources cover both paper and online certification examinations, but that does not independently establish that remote proctoring is available to you. Confirm your delivery method with VI when you apply. Timing details live in our CVA exam dates guide.

The Eight Preparation Headings

The eight domain names below reproduce the exact "Course Content Includes" headings on the current Introduction to Machinery Vibration page. They are unweighted preparation-curriculum headings, not a verified exam blueprint, and VI itself calls IMV partial preparation that references ISO 18436-2:2014. No official percentages exist for them, so do not allocate study time by invented weights. For the full walkthrough, read the CVA exam domains guide.

The domain lists above are study orientation, not a promise of what appears on your exam form. For a deeper look at how hard material in these areas tends to feel, see How Hard Is the CVA Exam?

The Older Competency Headings

The 2022 handbook's Body of Knowledge (pages 16-23) marks Category I topics under a different set of eight headings: Vibration Principles, Data Acquisition, Signal Processing, Condition Monitoring, Fault Analysis, Corrective Action, Equipment Knowledge and Acceptance Testing, referencing ISO 18436-2 Annex A. These remain a useful historical cross-reference, but they are not a reconciled current blueprint. If a practice question touches corrective action or acceptance testing, that is consistent with the older handbook even though the IMV headings do not list those names.

Equations, Calculator and Exam-Day Logistics

According to the 2022 handbook, the test is closed-book with equations supplied, a nonprogrammable scientific calculator is recommended for Category I, and smartphones and separate scrap paper are prohibited. These are historical handbook rules, not guaranteed current conditions, so verify them at registration.

• Do not memorize derivations. Practice using supplied equations quickly, including unit handling.
• Practice with a plain scientific calculator. Do not rely on a programmable or phone-based tool you may not be allowed to bring.
• Bring valid photo identification that satisfies VI's requirements, and expect ethics compliance as part of the process.
• Review the VI reference-equation resource for the paper and online exams so the equation sheet format is familiar.

Known Source Conflicts to Keep in Mind

VI's own published materials do not fully agree with one another, and an honest cheat sheet should say so rather than paper over it:

• The current HTML Body of Knowledge omits a Category I mark for Acceptance Testing, while the retrieved handbook and a Category I training-topic page include it.
• The current analyst-categories page repeats Data Acquisition under different topic groups and differs from the older handbook's category assignments.
• The newer 2025 handbook could not be retrieved from either linked host, so its contents are not assumed.

Five-Year Renewal Math

Certification lasts five years, and you can renew by points or by examination.

Do the arithmetic early: because experience is capped at 20 points, you cannot reach 23 on experience alone. Training and development must supply the remainder, and at 0.1 point per contact hour, small gaps require real hours. Track training certificates as you earn them rather than reconstructing them in year five.

Careers, Employers and Pay Expectations

Category I analysts typically work in reliability, maintenance and condition-monitoring roles, collecting and screening vibration data on rotating equipment, often within plants, service providers or consulting teams that run predictive maintenance programs. Browse the CVA jobs overview for the kinds of roles that value this credential.

Be careful with salary claims. Reliable guidance separates occupational experience and role-based earnings from any Category I-specific pay premium, and no verified premium figure exists to quote. Pay generally follows your role, industry, region and track record, with certification acting as evidence of competence rather than a guaranteed raise. The CVA salary guide and the ROI analysis treat this distinction in detail.

A Domain-Ordered Review Sequence

One short, CVA-specific ordering is enough. The logic is that later domains depend on earlier ones, so sequence by dependency rather than by interest:

A four-week frame is a template, not a rule; stretch it if you are new to the field. For a full plan, see the CVA study guide, then run timed sets in the practice test bank. If you want the broader overview of the program, start with CVA Certification.
