Although it has long been assumed that RTI will benefit ELLs by avoiding the types of biases associated with standardized testing, this premise does not appear to be wholly supported by research.

In describing a basic three-tier RTI model, one of the stated potential benefits included:

“Increased fairness in the assessment process, particularly for minority students”

“Teaching ELLs to read in their first language and then in their second language, or in their first and second languages simultaneously (at different times during the day), compared with teaching them to read in their second language only, boosts their reading achievement in the second language” (emphasis in original).

“The NLP was the latest of five meta-analyses that reached the same conclusion: learning to read in the home language promotes reading achievement in the second language.”

“Making an assumption that what works with native English speakers will work with students from diverse language backgrounds may be inaccurate (McLaughlin, 1992). Although substantial empirical support exists for the use of a response-to-intervention (RTI) approach to address literacy problems with native English speakers (e.g., Burns, Appleton, and Stehouwer, 2005; Mathes et al., 2005; Vellutino, Scanlon, and Tanzman, 1998), very little data exist about the effectiveness of this approach with EL learners (Vaughn et al., 2006).”

What exactly will evaluation look like beyond progress monitoring and curriculum based assessment of current academic skills?

How will these procedures systematically evaluate the influence of cultural and linguistic differences and the extent to which they are primarily responsible for lack of progress as compared to lack of progress due to a learning disability, particularly when RTI has not ensured that evidence-based instruction (i.e., in the native language) has been provided?
