What is CLB?

The Canadian Language Benchmark (CLB) is the national standard for measuring English-language proficiency in adult learners and immigrants. CLB runs from 1 (lowest) to 12 (highest), across four abilities:

• Listening
• Speaking
• Reading
• Writing

For French, the equivalent scale is NCLC (Niveaux de compétence linguistique canadiens), also 1-12 across the same four abilities.

CLB level descriptions (high level)

• CLB 1-4: Basic — can handle very limited communicative needs
• CLB 5-6: Initial intermediate — can handle everyday communication
• CLB 7-8: Adequate intermediate — can function in most workplace situations
• CLB 9-10: Advanced — can handle complex professional and academic communication
• CLB 11-12: Highly advanced — near-native fluency

CRS — language is the highest-leverage area

For Express Entry, CRS points scale with CLB level. Going from CLB 7 to CLB 9 typically adds 50-150 CRS points depending on profile. Language is the single highest-leverage area for most Express Entry candidates — invest in test prep before retaking.
