About

TunnelQuiz is a browser-based assessment platform for schools, coaching and certification providers, employers, and recruiting teams. Administrators can create multiple-choice, written-response, and coding tests, set timers and pass marks, shuffle questions, apply negative marking, and invite candidates through shareable links or bulk invitations. Proctoring tools record browser activity such as tab changes and full-screen exits, and may include webcam snapshots, identity checks, and alerts depending on plan. Teams can review responses and activity timelines, automatically score objective questions, manually or AI-grade supported written and coding answers on eligible plans, compare candidates, and export results. Candidates take assessments in a web browser without installing a separate test application.

Pros & Cons from Real Users

Pros

  • Their commercial software is somewhat comparable to other commercial softwares listed here. And appears to offer much the same features.
  • Nice that they have an open source product. Adequate for quizzing small groups of users when the results are not important.
  • That they do offer an open source product and do support a standard for question interoperability. Their offering is better than many others in this area.

Cons

  • That this statement about open source software somehow implies this is a better choice then the others listed here.
  • Their open source offering has a limit on the number of users and is not suitable for actual testing, only for simple quizzing (where is the ability to Resume a test if the users computer goes down? What do we tell the student?). PHP 7.x is end of life and should not be used. The QTI question format they use locks you into a limited, specific group of vendors (mostly commercial). QTI, the open standard they refer to is only endorsed by a very small group of commercial vendors worldwide (<800). Enterprise level support is only available if you pay. Where is the support for the Open Source version?
  • Their open source product is not an 'assessment solution' as there is not any analysis of the results provided. Considering the goal of assessment is the 'results', this is the most important information that needs to be conveyed by the software. Support of a single question standard limits your ability to move to other open source systems that may offer additional features.
