Learning Language Level Calibration

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

Composition

Input from: /curriculum.develop-content, /learning.translation Works with: /learning.cefr-alignment, /curriculum.review-accessibility Output to: Language-calibrated learning materials

Exit Codes

• 0: Calibration complete
• 1: Content too complex to simplify
• 2: Target level incompatible with content
