About
A teacher-authored English language teaching dataset covering the two intermediate CEFR levels, B1 and B2. It contains 200 lessons (100 per level, organised into 10 courses per level) with aligned native British English audio, plus an overview for each level and a high-level overview of the full corpus.
The lessons come from a 600-lesson A1 to C2 corpus written and recorded by a single author for The English Classroom, a teaching platform used by 7,000+ registered teachers in 80+ countries, including a UNRWA deployment. Each lesson is mapped to both a CEFR level and one of the UN Sustainable Development Goals, so the content is consistently levelled and tied to themes. B1 and B2 is where most learners sit and where many exam and workplace thresholds are set, which makes well-levelled material at this band particularly useful for training and evaluation. The rights position is clean: one author, no third-party material, and all rights held by The English Classroom AB.
Data Product Features
- CEFR level: every lesson is tagged B1 or B2
- Course structure: 20 courses in total (10 per level), each with sequenced lessons
- SDG theme: each lesson is mapped to one of the UN Sustainable Development Goals
- Lesson slides: instructional content written for intermediate learners, building towards independent use of English
- Teacher notes: a separate document for each lesson, keyed to slide numbers, in the same format across all 200 lessons
- Audio: native British English clips aligned to individual slides
- Activity types: a range of classroom activities within each lesson
- Level overviews: one overview document each for B1 and B2, summarising courses, lessons and progression
- Corpus overview: a high-level document describing the full A1 to C2 corpus
Distribution
The data product is delivered as lesson PDFs, SCORM packages (slides with per-slide audio), teacher-note PDFs and overview documents, organised by level, course and lesson. The audio is compressed as delivered within the lesson packages, and no uncompressed master recordings exist. Delivery is arranged after licence agreement, and a sample is available on request.
- Data Volume: 200 lessons (one record per lesson), 20 courses, 2 CEFR levels, 1000 audio clips, 2 level overviews and 1 corpus overview, approx. 0.7 GB
Usage
This data product is ideal for a variety of applications:
- LLM fine-tuning for intermediate learners: training models to produce or assess English at B1 or B2
- Proficiency classification: labelled examples for detecting intermediate-level text and the B1 to B2 boundary, where many exam and workplace thresholds sit
- Educational content generation: reference material for AI tutors, exam preparation and lesson-authoring tools
- Text-audio alignment: pairing lesson content with native-speaker audio for listening comprehension tasks and ASR evaluation
Coverage
The dataset covers the full intermediate band of the CEFR, where learners move towards independent use of English.
- Geographic Coverage: Global. The content is in British English and is used in teaching in 80+ countries.
- Time Range: 2019 - 2020
- Demographics: written for intermediate learners of English as a second or foreign language. All audio is by one adult native British English speaker.
