TELL aligns with World-Class Instructional Design and Assessment (WIDA™) English Language Development (ELD) Standards and other state standards.
External experts and ELL educators conducted standards alignment studies to investigate the degree of the alignment of TELL items and items types to the ELD standards of Arizona, California, Texas, and WIDA. These standards alignment studies examined the degree to which linguistic forms and language functions identified in a set of ELD standards are covered by TELL items. They also evaluated how consistent the coverage is when broken out by grade or grade band, skill domain, and item type.
In particular, these alignment studies provide information about how well TELL items address the language features of the standards that articulate expectations for the development of English in a K–12 context.
Reports concluded that a close alignment exists between TELL and the ELD standards of Arizona, California, Texas, and WIDA, indicating that it adequately covers those standards and can be integrated with confidence into the instructional program.
The relationship between TELL overall scores and scores on other large-scale ELD assessments was established through a large data collection. Our resulting score concordance tables allow you to estimate how a student might score on a summative language proficiency assessment based on his or her TELL results.
The four large-scale assessments mapped in this way are WIDA ACCESS for ELLS®, AZELLA, CELDT, and TELPAS. These concordance tables help make TELL scores more meaningful for teachers and administrators:
|Large Scale Language Assessment||Score That Can Be Estimated||Grade Bands|
WIDA ACCESS FOR ELLs (Assessing Comprehension and Communications in English State-to-State for English Language Learners)
|Overall Score||K, 1-2, 3-5, 6-8, 9-12|
|AZELLA (Arizona English Language Learner Assessment)||Total Combined Score||1-2, 3-5, 6-8|
|CELDT (California English Language Development Test)||Overall Score||1, 2, 3, 4, 6|
|TELPAS (Texas English Language Proficiency Assessment System)||Composite Score||1, 2, 3, 4, 5, 7|
