Learning Language Level Calibration

Calibrate educational content difficulty for language proficiency levels and multilingual learners.

When to Use

• Creating content for English Language Learners (ELL/ESL)

• Adapting for multilingual classrooms

• Language-sensitive subject instruction

• Supporting non-native speakers

• International student programs

Proficiency Frameworks

CEFR Levels (Common European Framework)

• A1 (Beginner): Basic phrases, simple interactions

• A2 (Elementary): Routine tasks, simple descriptions

• B1 (Intermediate): Main points of clear input, workplace basics

• B2 (Upper Intermediate): Complex text, spontaneous interaction

• C1 (Advanced): Implicit meaning, flexible language use

• C2 (Proficient): Subtle distinctions, near-native fluency

Other Frameworks

• ACTFL (American Council): Novice, Intermediate, Advanced, Superior, Distinguished

• ILR (Interagency Language Roundtable): 0-5 scale

• Cambridge English: KET, PET, FCE, CAE, CPE

Calibration Factors

Vocabulary Complexity

Word Frequency:

• A1-A2: Most frequent 1,000-2,000 words

• B1-B2: 3,000-5,000 words

• C1-C2: 8,000+ words, academic vocabulary

Technical Terms:

• Glossary support needed

• Visual aids

• Translations or explanations

Sentence Structure

Complexity by Level:

• A1-A2: Simple sentences, present tense focus

• B1-B2: Compound sentences, various tenses

• C1-C2: Complex subordination, passive voice, conditionals

Text Length

Appropriate Length:

• A1: 50-100 words per section

• B1: 200-300 words

• C1: 500+ words, longer paragraphs

Cultural Load

Background Knowledge:

• Explicit cultural references

• Idioms and expressions

• Implicit meanings

Adaptation Strategies

Simplification

Techniques:

• Break long sentences

• Use active voice

• Replace rare words with common alternatives

• Add visual supports

• Provide glossaries

Scaffolding

Language Supports:

• Sentence frames

• Word banks

• Graphic organizers

• Multilingual glossaries

• Translation aids (strategic, not crutches)

CLI Interface

Assess content level

/learning.language-level-calibration --content "lesson.md" --estimate-level

Adapt to target level

/learning.language-level-calibration --content "advanced-text.md" --target-level "B1" --output simplified.md

Create scaffolded versions

/learning.language-level-calibration --content "article.md" --levels "A2,B1,B2,C1" --output levels/

Readability metrics

/learning.language-level-calibration --content "course/" --metrics "CEFR,Flesch-Kincaid,Lexile"

Output

• Language proficiency level assessment

• Vocabulary analysis (frequency, academic word list)

• Sentence complexity metrics

• Adapted content at target levels

• Scaffolding recommendations

Exit Codes
