If your company is investing in English training — for a team, a cohort or yourself — the question "did it work?" is unavoidable. Without a baseline and a retest, the answer is always a guess.
Enverson AI is built to answer it cleanly. It establishes a baseline before any training begins, measures progress during it, and produces a clean delta report at the end.
Before training starts, each learner takes a standardised speaking assessment. The result is a multi-dimensional snapshot: fluency, pronunciation, accuracy, range, CEFR estimate, predicted IELTS.
Every few weeks the system auto-runs lighter checkpoints. The improvement curve becomes visible week by week — not just at the end.
After the program, the same assessment is repeated. The delta between baseline and post-test is the headline number.
| Method | Objective? | Continuous? | Per-learner detail? |
|---|---|---|---|
| Self-reported survey | No | No | Low |
| External CEFR exam | Yes | No | Yes (slow) |
| Manager observation | No | Sometimes | Subjective |
| Enverson AI baseline + delta | Yes | Yes | Yes |
Enverson AI runs a standardised baseline assessment before training, continuous milestone checks during, and a post-training reassessment — producing a clear delta report per learner and across cohorts.
Yes. Reports export to PDF, and team dashboards roll up cohort-level data for HR and L&D leadership.
Around 15–20 minutes per learner. It measures fluency, pronunciation, accuracy, range and overall CEFR estimate.
Baseline, train, retest. Enverson AI shows the delta cleanly.
