Formal Methods & Software Verification Certification

The Formal Methods & Software Verification Certification is a free advanced-level, 25-minute skill test from Science of Apps. It tests formal methods and software verification — specifications versus implementations, safety and liveness properties, invariants, pre- and postconditions and Hoare logic, model checking and state-space explosion, temporal logic such as LTL, TLA+ specifications and the TLC model checker, SAT and SMT solvers, symbolic execution, abstract interpretation and static analysis, theorem proving with Coq/Rocq, Lean and Isabelle, verified programming in Dafny, refinement, property-based testing and fuzzing as lightweight methods, industrial use at AWS and in avionics and chips, and the limits and costs of verification — written to TLA+, Software Foundations, Dafny and industry experience reports for 2026 and 2027. Score 70% or more on its 25 questions to earn a verifiable Formal Methods & Software Verification certificate (SOA-FMSV). Every question is based on published standards and research — including Software Foundations (Coq/Rocq) (Benjamin Pierce et al., University of Pennsylvania), TLA+ and the TLA+ Toolbox (Leslie Lamport and the TLA+ Foundation), Dafny reference and tutorials (Dafny project) — and each answer is explained with its source.

Science of Apps offers a free Formal Methods & Software Verification Certification, written for 2026 and 2027. It tests specification foundations, model checking, solvers and analysis, theorem proving and practice and trade-offs with 25 original scenario questions in all, each naming its published source; you get an instant score and a verifiable certificate with a credential ID you can add to LinkedIn.

Read the five skill areas on this page, then take the 25-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Formal Methods & Software Verification certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Software Foundations (Coq/Rocq) (Benjamin Pierce et al., University of Pennsylvania); TLA+ and the TLA+ Toolbox (Leslie Lamport and the TLA+ Foundation); Dafny reference and tutorials (Dafny project); How Amazon Web Services Uses Formal Methods (Newcombe et al., Communications of the ACM (2015)); What is Lean? (Lean Enterprise Institute); Haskell documentation and the Haskell 2010 Report (haskell.org). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Specification Foundations (Specifications, Safety and liveness and Invariants and contracts); Model Checking (State spaces, Temporal logic and TLA+ in practice); Solvers and Analysis (SAT and SMT, Symbolic execution and Static analysis); Theorem Proving (Proof assistants, Verified software and Refinement); Practice and Trade-offs (Lightweight methods, Industrial use and Choosing methods). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Software or systems engineer, Distributed systems or protocol designer, Security or safety-critical engineer, Hardware verification engineer and Computer science graduate student. It suits students at leading universities, career switchers and experienced professionals who want quick, verifiable proof of Formal Methods & Software Verification knowledge in 2026 and 2027.

CS and AI students at MIT, Stanford, CMU, Berkeley, IITs, Tsinghua and ETH are hired on depth beyond tool use: model internals, systems and hardware. Passing earns a founder-signed Science of Apps certificate with a credential ID and QR code that recruiters can verify.

A safety property says something bad never happens (for example, two leaders never exist at once). A liveness property says something good eventually happens (for example, every request is eventually answered).

Automatically exploring all reachable states of a finite model to check whether a specification holds, producing a counterexample trace when it does not.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

25 questions — 5 from each of 5 skill areas — with a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 25 scenario questions — 5 from each of 5 skill areas — and a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
