CEFR stands for The Common European Framework of Reference for Languages and is used as an international guideline for language ability, especially in Europe. (A0–C2)
CLB stands for The Canadian Language Benchmarks and is a scale of language ability used in Canada. (1–12)
TOEIC, TOEFL, and IELTS are standardized tests.
ELD stands for English Language Development standards. This equivalency is based on numeric proficiency scales commonly used in K–12 programs. WIDA (US) uses these descriptors:
Level 1 Entering
Level 2 Emerging
Level 3 Developing
Level 4 Expanding
Level 5 Bridging
Level 6 Reaching
See WIDA PRIME V2 Correlation for Ellii here. For more information on how Ellii aligns with WIDA, view this summary. (Note: Ellii was formerly known as ESL Library.)
NRS refers to the National Reporting System for Adult Education. The descriptors for English as a Second Language (ESL) in the NRS system are divided into six educational functioning levels: Beginning ESL Literacy (1), Low Beginning ESL (2), High Beginning ESL (3), Low Intermediate ESL (4), High Intermediate ESL (5), and Advanced ESL (6).
