CAL's Adult ESL Assessments

The number of adult English language learners in the United States continues to grow substantially and programs serving them face many challenges in providing instruction to meet their needs. Having tests that are appropriate, valid, and reliable is critical to the evaluation of oral and written English proficiency for this growing population. CAL understands these challenges and can help programs determine the best combination of assessments to meet the needs of both the programs and the students.

BEST Literacy and BEST Plus 2.0 address the needs of adult English language learners by providing assessment options that reliably demonstrate student progress. With BEST Plus 2.0 to measure speaking and listening skills and BEST Literacy to measure reading and writing skills, programs can test all of the four skill areas. Both assessments are aligned to the National Reporting System and the Student Performance Level ESL descriptors.
