IdiomIQ Adaptive Placement Test

Students take a short, adaptive CEFR test on your page, and you receive their email address together with an accurate A2–C2 level — notified by email and logged in your WordPress dashboard. Give visitors something genuinely useful, an instant read on their language level, and get something valuable back: a lead you can actually act on, with no wasted discovery calls.

How it works

1. Add it to any page. Paste the shortcode wherever you want the test. Works with any theme — no code or developer required.
2. Visitors take the test. The adaptive algorithm adjusts difficulty in real time. No account, no app, no download.
3. You receive a qualified lead. You capture their email the moment they start, and their CEFR level the moment they finish.

Why adaptive?

Instead of asking everyone the same fixed list, the test targets each student’s ability and reaches an accurate CEFR estimate in far fewer questions. Under the hood it uses a Bayesian EAP estimator with an Item Response Theory (3PL) model — the approach behind professional adaptive exams — but your visitors just see a fast, fair test.

Privacy Policy

This plugin collects and stores personal data as described below. All data is held in your site’s own database. The free plugin does not transmit personal data to any third party.

Data collected per test attempt

• Student email address — entered voluntarily before the test begins; used to deliver results by email and stored in the attempt log.
• Test outcome: CEFR level, ability estimate (theta), standard error, and test duration — stored alongside the email to allow administrators to review attempt history.
• Date and time of the attempt.

Storage location: The {prefix}iiqapt_attempt_logs database table on your own server.

Retention period: Configurable under Settings → IdiomIQ Adaptive Placement Test → General Settings → Log Retention. The default is 90 days; a daily scheduled event automatically removes records older than this threshold. Administrators can also delete individual records or the entire log from the Attempt Logs admin tab.

Data deletion on uninstall: If Delete data on uninstall is enabled in General Settings, all plugin database tables and stored options are permanently removed when the plugin is uninstalled via the WordPress admin.

Rate limiting

To prevent automated abuse, a hashed representation of the visitor’s IP address (MD5 hash — the raw address is not stored) is written to a WordPress transient at the start and submission of each test attempt. These transients expire automatically after one hour and are not retained as long-term records.

Recommended site owner disclosure

Site owners should include the following information in their own Privacy Policy:

“When you take the English level test, we collect your email address and store your result (CEFR level and score) in our database. This information is used to send you your results and to allow our team to review outcomes. Records are automatically deleted after [your configured retention period] days. Your IP address is temporarily hashed and stored for up to one hour for abuse-prevention purposes only.”
