MOS - Microsoft Office Specialist Trainings

MOS certification in Geneva: validating Microsoft Office skills with a recognised exam

The Microsoft Office Specialist (MOS) programme is Microsoft’s official certification scheme for consumer Microsoft 365 applications: Excel, Word, PowerPoint and Outlook. Each application offers an Associate-level exam, and some include an Expert level (Excel and Word) for advanced profiles. The ITTA MOS catalogue, delivered in Geneva and Lausanne, prepares for the 2019 version, the 2021 version and the current Microsoft 365 version exams, depending on each candidate’s needs.

Why get MOS certified?

Many candidates mention “Excel proficiency” or “good Word skills” in their CV, but these statements remain subjective and hard to objectivise during recruitment. MOS certification provides tangible and defensible proof: an exam score on a standardised Microsoft grid, a numeric score out of 1000, and an official badge shareable on LinkedIn and in applications. For early-career profiles, career changers or those seeking advancement, this is a strong signal. For employers, it is an objective criterion to differentiate applications. For public services and certain funded bodies, it is also a recognised framework to validate office skills within a continuous training journey.

MOS Excel Associate and Expert

The MOS Excel Associate certification validates daily skills: workbook and sheet management, conditional formatting, common formulas (IF, VLOOKUP, XLOOKUP, SUMIF, COUNTIF), structured tables, sorting and filtering, basic charts, printing and sharing. The MOS Excel Expert certification goes further: advanced lookup and logical functions (LET, LAMBDA in Microsoft 365), complex pivot tables, Power Query for data transformation, custom number formats, introductory macros and VBA, workbook templates. This is the expected level for analysts, controllers, accountants and data profiles.

MOS Word Associate and Expert

The MOS Word Associate certification covers structured document creation: text and paragraph formatting, styles, headers and footers, tables of contents, object insertion (images, tables, charts), collaborative review, print options. The MOS Word Expert certification addresses advanced features: complex templates, mail merge, forms, multi-section documents, reference management (table of illustrations, index, bibliography), macros and automation. It is appreciated by legal secretariats, HR departments and communications officers producing structured documents regularly.

MOS PowerPoint and MOS Outlook Associate

The MOS PowerPoint Associate certification validates the creation of a professional presentation: slide masters, layout, restrained transitions and animations, media insertion, timeline management, using Designer for layout suggestions, and presenting in presenter mode. The MOS Outlook Associate certification covers effective inbox and calendar management: inbox organisation (rules, folders, search, categories), contact management, Teams meeting planning, calendar sharing, task and note management. Both certifications are useful complements for communications, training, reception and administrative roles.

Preparing for MOS exams at ITTA

ITTA MOS training is organised in two phases: a skill-building phase covering the full Microsoft framework for the target exam, and an exam preparation phase (timing, simulations on the Certiport platform, common pitfalls). Courses are offered in short formats (2 to 3 days per exam) and in combined paths to prepare for several certifications in sequence. MOS exams are taken on a workstation with access to the Microsoft application in real conditions, with tasks to complete within a set time.

Learning formats

MOS training takes place in Geneva and Lausanne on-site or in synchronous remote mode. Sessions alternate between short theoretical inputs and continuous hands-on practice on Microsoft applications. Official MOS exams are taken on the Certiport platform; ITTA can organise the exam in connection with the training. The score is displayed immediately at the end of the exam, and the candidate receives a digital certificate shareable on LinkedIn and with employers. Candidates targeting several certifications benefit from training in a logical order: MOS Excel Associate before Excel Expert, MOS Word Associate before Word Expert.

Frequently asked questions on MOS certifications

What score is required to pass a MOS certification? The passing score varies by exam but generally sits around 700 points out of 1000. The exact score is not communicated publicly by Microsoft and may evolve with exam revisions. ITTA prepares candidates to comfortably exceed the threshold, with timed simulations on the Certiport platform at the end of training.

Which Office version should one choose for the exam? Microsoft offers MOS exams on three versions: Office 2019, Office 2021 and Microsoft 365 Apps. For a candidate using a Microsoft 365 environment daily, choosing the 365 version is coherent. For a workstation locked on Office 2019, that version is better to avoid interface gaps. ITTA recommends aligning the training version with the candidate’s real work environment.

Is the MOS certification valid indefinitely? Yes, MOS certification is valid for life on the version of the exam taken. In practice, older versions (MOS 2016, 2019) remain recognised but are gradually replaced in employer requirements by versions 2021 and Microsoft 365. A candidate certified on 2019 can later target a 2021 or 365 certification to refresh their CV.

MOS Master: combining several certifications

Microsoft offers a MOS Master recognition for candidates who obtain several MOS certifications: typically Word Expert, Excel Expert, PowerPoint Associate and an additional certification of choice (Outlook or Access). This recognition signals a versatile and expert profile across the Office suite, particularly valued for executive assistant, administrative manager, controller, financial analyst or communications officer roles. ITTA advises MOS Master candidates on a learning path spread over 3 to 6 months, with progressive upskilling and exam attempts spaced out.

MOS and CV value

MOS certification brings tangible value on the French-speaking Switzerland job market. For early-career profiles, career changers and those seeking advancement, it signals seriousness and operational mastery. For employers, it is an objective criterion that goes beyond self-declared skills. On the visibility side, the official Microsoft Certified badge integrates into LinkedIn profiles (with a direct link to the Credly credential), can be inserted in email signatures and appear on the CV. For organisations training their staff, displaying a MOS certification rate within a team is a differentiating argument in tenders or client presentations. ITTA also supports companies in the collective deployment of MOS certification, with in-company sessions and centralised exam scheduling.
