End-to-end certification platform built by psychometricians
Subject-matter experts and reviewers write, comment on, and approve exam questions in a shared workspace with version control and workflow states.
Statistical review of item difficulty, discrimination, and reliability is handled inside the platform, so exams stay defensible for accreditation and audits.
Candidates schedule and take exams remotely or at test centers, with configurable proctoring and identity verification options.
The platform is designed to compress the timeline from concept to first live exam, avoiding lengthy enterprise procurement and implementation cycles.
Build powerful forms, surveys and quizzes with AI in minutes
Describe the form you need in plain language and Zite generates a branded form with logic, file uploads, and payments.
Add conditional logic, intelligent routing, and multi-step workflows to automate what happens after each response.
Respondents can log in to update their answers, and forms can be restricted to internal users only.
Use custom themes, fonts, logos, custom CSS, your own domain, and embed forms as popups, sliders, or full-screen pages.
