详情介绍:
IdiomIQ Adaptive Placement Test delivers a personalised English placement test that dynamically adjusts to each student's ability level. Rather than presenting every question in a fixed order, the algorithm selects the next question based on the student's previous answers, reaching an accurate CEFR estimate with far fewer questions than a traditional fixed-length test.
How it works
- Each question is answered by the student.
- A Bayesian EAP estimator continuously refines the ability estimate (theta) and its standard error.
- The quiz stops automatically once the standard error falls below your configured target confidence, or after the maximum number of question batches.
- The estimated CEFR level (A2 through C2) is displayed on a results screen and emailed to the student.
- Adaptive algorithm: Bayesian EAP with Item Response Theory (IRT) 3PL model
- CEFR levels: A2, B1, B2, C1, C2
- Question banks: unlimited banks and questions per bank
- CSV import: bulk upload questions with level, stem, and four answer options
- Email results: configurable student and admin notification emails
- Attempt log: searchable, sortable log with CSV export
- Dyslexia-friendly font toggle (OpenDyslexic, SIL OFL 1.1)
- GDPR follow-up consent checkbox
- Honeypot spam protection
- Rate limiting to prevent abuse
- Configurable log retention with daily automated cleanup
- Fully built on the WordPress Settings API — no custom admin framework
[iiqapt]
To use a specific question bank:
[iiqapt bank="2"]
Source code
Development takes place on GitHub.
安装:
- Upload the
idiomiq-adaptive-placement-testfolder to/wp-content/plugins/, or install directly from the WordPress plugin directory. - Activate the plugin through the Plugins menu.
- Go to Settings → IdiomIQ Adaptive Placement Test to configure question banks, email templates, and quiz behaviour.
- Add
[iiqapt]to any page or post where you want the test to appear. - Import questions via Questions → Import CSV, or add them individually through the admin interface.

常见问题:
What is CEFR?
The Common European Framework of Reference for Languages (CEFR) is an international standard for describing language ability. This plugin assesses levels A2 (Elementary) through C2 (Mastery).
How does the adaptive algorithm work?
The plugin uses a Bayesian EAP (Expected A Posteriori) estimator combined with a 3-Parameter Logistic Item Response Theory (IRT) model. After each answer, it updates the probability distribution over the student's ability level and selects the question that provides the most information given the current estimate. The test stops when the standard error falls below your configured target or the maximum number of question batches is reached.
What CSV format is required for importing questions?
Columns in order: question_stem, option_a, option_b, option_c, option_d, correct_answer, cefr_level. The correct_answer field should be the letter A, B, C, or D. The cefr_level field must be one of: A2, B1, B2, C1, C2.
Can I run multiple tests on the same site?
Yes. Create additional question banks under Questions → Manage Banks and use the bank shortcode attribute to target each one: [iiqapt bank="2"].
更新日志:
1.3.4
- Fixed a MySQL syntax error logged on activation — the questions index is now declared in the table schema (dbDelta) instead of an unsupported
CREATE INDEX IF NOT EXISTSstatement.
- Security: added explicit capability and nonce verification to the settings save-tracking notice before any state is written.
- Fixed the Plugin URI to point to the live plugin page.
- Standardised all internal code naming to a single
iiqaptprefix (functions, options, database tables, CSS/JS, hooks). - The shortcode is now
[iiqapt](previously[adaptive_level_test]). - Reordered the settings tabs — Attempt Logs first, General Settings last.
- Adaptive algorithm: a top-level (C2) student now continues until the confidence target or batch limit, symmetric with the A2 floor.
- Renamed plugin to IdiomIQ Adaptive Placement Test.
- Removed question bank and question count limits — the free plugin is now fully unlimited.
- Converted all inline script and style tags to use the WordPress enqueue API.
- Extracted admin JavaScript to external files for better caching and CSP compatibility.
- Initial public release as a standalone free plugin.
- Core adaptive quiz with Bayesian EAP / IRT 3PL algorithm.
- Unlimited question banks and questions per bank.
- CSV import for bulk question upload.
- Student and admin result notification emails.
- Attempt log with search, sort, per-column filtering, and CSV export.
- Dyslexia-friendly OpenDyslexic font toggle.
- GDPR follow-up consent checkbox and honeypot spam protection.
- Rate limiting via hashed IP transients (1-hour TTL).
- Configurable log retention with daily scheduled cleanup.
- Option to delete all plugin data on uninstall.
