About PracticeCLB

PracticeCLB is an independent AI-powered CELPIP practice platform built for Canadian immigration candidates. It provides instant AI scoring for Writing and Speaking, along with adaptive practice for Reading and Listening — so you can know your CLB level before test day.

Built by a solo developer in Ottawa, Ontario. We are not affiliated with Paragon Testing Enterprises or any official CELPIP testing body.

Our AI Scoring

Our AI evaluates Writing and Speaking responses against CELPIP-aligned rubrics, delivering a CLB level estimate with detailed band-by-band feedback in seconds. The scoring model is transparent — you can read exactly how it works, what criteria it applies, and why it assigns each score. See the Score Trust page for full details.
