The fine print

What are the retake and renewal rules for the Microsoft Office Specialist: Expert?

Proctoring & delivery

Delivered by Pearson VUE. You can sit the exam at a Pearson VUE test center or take it online through OnVUE remote proctoring; the fee is the same for both. Online proctoring requires a quiet, private space, a working webcam, and a system check beforehand.

Retake policy

If you do not pass, you may retake the exam after 24 hours. A second failed attempt requires a 14-day waiting period, and any further attempts also require a 14-day wait between them, up to a maximum of five attempts in a 12-month period.

Score reporting

A pass/fail result is shown immediately after the exam. The official score report is emailed within about 24 hours and is also available in your Microsoft certification profile, with section-level feedback on how you performed.

Recertification

Microsoft role-based, specialty, and fundamentals certifications are valid for 12 months from the date earned. Renew at no cost by passing the shorter online renewal assessment on Microsoft Learn before the credential expires. Retired certifications cannot be renewed and must be re-earned through the active successor if one exists.

Refunds & rescheduling

Exam fees are generally non-refundable once a seat is purchased, but you can cancel or reschedule through Pearson VUE at no charge if you do so at least 24–48 hours before the appointment (exact window varies by region).

What it pays

How much does this credential pay?

The MOS Expert credential evidences advanced Word, Excel or Access skill: secretaries and administrative assistants earned a $47,460 median in May 2024 (BLS), and expert-level spreadsheet and document skill feeds analyst and coordinator roles

The Microsoft Office Specialist (MOS) Expert certification evidences advanced hands-on proficiency in the hardest Office applications - Word Expert, Excel Expert and Access Expert - and it is positioned by Microsoft as the highest credential in the MOS program. It is a vendor certification, not a job license, so no single BLS SOC code attaches to it; the salary story belongs to the office and analytical occupations that use these applications at a demanding level. BLS reported that secretaries and administrative assistants, except legal, medical and executive (SOC 43-6014), earned a median of $47,460 in May 2024, with about 3,453,100 jobs and roughly 358,300 openings projected per year over 2024-2034, and the honest framing is that Expert-level Excel and Word skills most directly support analyst, coordinator, operations and business-support roles that sit at or above that median rather than the entry-level clerical range. The structural point is that the MOS Expert credential requires the Associate credential plus two Expert exams, so it is a stacked signal: it proves the candidate mastered the advanced features - custom functions, pivot tables, data analysis and macros in Excel; styles, mail merge, long-document tools and document automation in Word; database design and multi-table queries in Access - not just the everyday ones. BLS classifies workers by occupation, not certifications, so no certificate maps to a specific wage; the value is the verifiable signal in a market where advanced spreadsheet and document automation separate candidates. Each Expert exam is performance-based (the candidate completes tasks in the actual application), costs about $100 (with discounts through schools and programs), and the exams do not expire. The honest caveat: BLS projects little or no change in the secretarial occupation through 2034, so the credential is a differentiator for the roles that pay at the upper end of the office range, and the strongest wage case is made by pairing it with analyst-track job titles rather than expecting the certificate itself to move a wage.

Your schedule

How long should I study for it?

80-150 hours over 10-16 weeks of focused study

A realistic MOS Expert plan runs 80-150 hours over 10-16 weeks for a candidate who already holds the Associate credential, because the Expert path requires passing two Expert exams at a significantly higher difficulty than the Associate exams and the fastest gains come from building on the Associate-level fluency rather than starting over. The single highest-yield planning decision is to confirm which two Expert exams you will take - Word Expert (MO-101), Excel Expert (MO-201) or Access Expert (MO-500) - because the prerequisites differ in length and the Excel and Word Expert exams are the most common pairing for business roles, while Access Expert is the deep-database option. The plan should split into exam-by-exam preparation: weeks 1-5 for the first Expert exam, weeks 6-10 for the second, and weeks 11-16 for timed practice tests and the sittings; candidates preparing for only two Expert exams should plan 10-12 weeks total. Each Expert exam’s preparation follows the same pattern but at a higher depth: review the published objectives document for the Expert level, practice the advanced features hands-on (in Excel: advanced formulas, functions, pivot tables, data analysis and macros; in Word: styles, mail merge, long-document tools, document automation and digital signatures; in Access: database design, relationships, multi-table queries, forms and reports), then complete a Certiport GMetrix practice test at the Expert level before sitting. Candidates with strong Associate-level skills in the chosen apps should budget the lower end and weight time toward the Expert gap features; candidates moving up from a single-app Associate credential should budget the upper end and add review of the apps they will not re-test. The budget should include the two Expert vouchers at about $100 each, the GMetrix practice tests at roughly $20-30 each, and the Associate prerequisite if not already held. The final week before each Expert exam should include at least one full timed practice test scoring above 700, because the advanced tasks are more time-demanding than the Associate format.

What to buy

Which study resources are worth paying for?

The MOS Expert resource market has a clear official core and modest paid options, and the buying logic is the same as the Associate level but with more weight on practice volume because the advanced tasks are harder. The Microsoft Learn training modules are free for each Expert exam and map to the objectives; Microsoft also publishes the free Expert objectives documents that are the exam blueprints. Hands-on practice requires only the desktop applications (a Microsoft 365 subscription or work/school account covers the full suite, which the exams test). The Certiport practice tests (GMetrix) cost about $20-30 each and are the closest match to the harder performance-based format; for Expert exams they are close to essential because the advanced-task timing is the main failure mode. Commercial MOS Expert prep books ($30-$50 each) and courses ($100-$500 per app) add structure and practice projects, and their value is practice volume rather than unique content; the Expert editions are the ones to choose because the Associate editions do not cover the advanced objectives. The exam fees are about $100 each (with frequent discounts through schools, libraries and workforce programs - candidates should check with their school or local workforce center for free or discounted vouchers, which is the single largest saving on this credential). Candidates who already hold the Associate credential have the desktop licenses and the objectives documents in hand, so the marginal purchases are the two GMetrix practice tests and the two exam vouchers. The honest ranking: free Microsoft Learn modules and the objectives documents, desktop-app practice, the GMetrix practice tests, and a course only for structure. Prices here are current as of mid-2026 and change frequently; we rank nothing by commission.

What you'll face

What question types will I see?

The MOS Expert credential consists of the Associate prerequisite plus two performance-based Expert exams, each about 50 minutes with multiple projects of advanced tasks completed in the actual application and a passing score of 700/1000. For the Office 2019 program, the Expert exams are MO-101 Word Expert, MO-201 Excel Expert and MO-500 Access Expert, and candidates pass any two; for the Microsoft 365 Apps program, candidates pass the Word Expert and Excel Expert exams. The published Expert objectives are a superset of the Associate objectives: Word Expert covers managing document options and settings, advanced editing and formatting, creating and managing references, and creating and managing mail merges; Excel Expert covers managing workbook options and settings, applying custom data formats and layouts, creating advanced formulas, and creating advanced charts and tables; Access Expert covers managing databases, creating and modifying tables and relationships, creating and modifying queries, and creating and modifying forms and reports. Because the exams are performance-based, tasks ask the candidate to produce an advanced result in the application rather than select an answer, and the task style rewards knowing exactly where the advanced features live in the desktop ribbon; each exam interface includes a task list that supports the skip-and-return pacing strategy, and each Expert exam is scored independently at the same 700/1000 bar, so a candidate can pass one Expert exam and retake the other without restarting. The samples below illustrate the Excel Expert and Word Expert task styles, including a pivot-table scenario, a lookup-function item and a mail-merge scenario, which are representative of the advanced content the Expert objectives publish. The samples are editor-written illustrations of the published objectives, not live exam items.
