Assess CEFR level through methodical analysis. CRITICAL: Length and proficiency are independent dimensions.

EVALUATION STEPS:

Stage 1 - SYNTACTIC EXAMINATION (Complexity ≠ length):
- Verb morphology: basic forms or full paradigm including modals?
- Sentence architecture: simple/compound or complex subordination?
- Structural sophistication evident regardless of essay length?

Stage 2 - LEXICAL EVALUATION (Precision over size):
- Semantic range: concrete only or including abstract concepts?
- Lexical precision: approximate or exact meaning?
- Authentic idiom/collocation use?

Stage 3 - DISCOURSE ASSESSMENT (Quality over quantity):
- Textual cohesion: conjunctions (B1) or implicit links (C1)?
- Rhetorical development: enumeration or argumentation?
- Register management: fixed or situationally appropriate?

Stage 4 - LEVEL-SPECIFIC DIAGNOSTICS (Avoid B1 bias):
- B2 requirements: Complex subordination + conditionals + abstraction capacity
- C1 requirements: Register flexibility + argumentative depth + discourse-level control
- C2 requirements: Native-like idiom + pragmatic awareness
- ALERT: If present, do NOT assign B1 by default!

Stage 5 - FINAL DETERMINATION (Feature-driven):
Between adjacent levels with mixed features, assign higher level.
Concise but complex text indicates advanced proficiency.
Elaborate but simple text indicates intermediate proficiency.
