Who it's for: organisations that test people

Large candidate lists, strict timing, proctoring and results you can publish with confidence.

NGOs and programmes

Screen applicants and certify participants at the end of a programme.

Businesses

Recruitment tests and staff training assessments, with certificates for those who pass.

Everything from the first question to the certificate

Questions

• Question banks: single- and multiple-answer multiple choice, true/false, fill-in-the-blank, short answer, numeric and essay questions.
• AI question drafting: Summy, our AI, drafts a whole bank, adds questions to one, or drafts an assessment from your prompt — you review before anything is used.
• Import what you have: bring existing questions in from a file and check them before they’re saved.

Assessments and candidates

• Assessment builder: sections, question banks, timing, randomisation, marking schemes and grading bands.
• Bulk candidate import: upload a CSV of candidates, map its columns, fix any problems it flags, then import.
• Proctoring and invigilation: each attempt records tab switches, leaving full screen, copy-paste attempts and more; webcam proctoring flags no face, several faces or looking away. A person reviews the flags.

Your portal

• Your own address: candidates sit exams at yourname.sumclash.com, at exam.sumclash.com, or on your own custom domain.
• Your branding: your organisation’s name, logo and colours on the portal your candidates see.
• Candidate sign-in: candidates sign in to your portal to sit the assessments assigned to them.

Results and beyond

• Results: score, rank, percentile and pass/fail per candidate — release them when you’re ready, and export them.
• Verifiable certificates: signed certificates with a code and a QR anyone can check, no login needed. Revoke one if you have to.
• Automation: event, condition, action — email a candidate, release a result or issue a certificate automatically.
• Offline CBT centres: run an exam on a centre’s local network with no internet: the exam goes out as an encrypted package and results come back as an upload.
• API and webhooks: read assessments, candidates and results over a REST API with scoped keys, and receive signed webhooks.
• Accommodations: rest breaks and other accommodations for candidates who need them.

How it works: from sign-up to certificates

1. Register your organisation. You choose your portal address — yourname.sumclash.com — and manage everything from your organisation dashboard.
2. Build your questions. Write them, import them, or have Summy draft them. Organise them into banks.
3. Set the assessment and add candidates. Choose sections, timing and marking, then add candidates one by one or from a CSV.
4. Candidates sit it; you release results. They sign in on your portal. You review, publish results and issue certificates.

Questions people ask first

Where do candidates sit the exam?

On your organisation’s portal — your own yourname.sumclash.com address, exam.sumclash.com, or a custom domain on Premium and Enterprise. It works in any modern browser; nothing to install.

Can I start without paying?

Yes. The Free plan covers 50 candidates a month, 5 assessments and 3 question banks, so you can run a real assessment before you choose a plan.

How are certificates verified?

Every certificate is signed and carries a code and a QR code. Anyone — an employer, a school — can check it without an account. A revoked certificate shows as revoked.

Can we run exams where the internet is unreliable?

On Enterprise, yes: an offline CBT centre runs the exam on its local network. The exam arrives as an encrypted package, the key is released separately, and results are uploaded when you’re back online.

Does proctoring decide who cheated?

No. It records what happened during an attempt — tab switches, leaving full screen, webcam flags — and scores the risk. A person on your team makes the decision.

I’m a candidate. Where do I sign in?

Use the link or sign-in details your organisation sent you, or go to exam.sumclash.com/login.
