Children who speak a language other than English at home and are learning English as their second language can vary widely in their exposure to and opportunity for learning English. This can make testing a challenge because unbiased testing depends heavily on controlling for these differences. In this workshop, Dr. Ortiz will discuss innovative ways to achieve greater fairness and equity in testing.
Join Dr. Samuel Ortiz, author of the C-LIM and Ortiz PVAT, as he discusses tools and procedures he has created to reduce bias and increase accuracy when testing bilingual students.

Same-age English learners (ELs) can vary widely in their exposure to and opportunity for learning a second language. Unbiased testing thus depends heavily on controlling for these differences in development. In this webinar, Dr. Ortiz discussed innovative ways to achieve greater fairness and equity in testing.
Participants will:
- Identify the limitations of current approaches to testing English learners with respect to validity
- Explain the need for “true peer” group comparison to establish diagnostic validity of test results
- Explain how language development differences are controlled within the EL normative sample in the

language background
