Test Accessibility and Modification Inventory
The Test Accessibility and Modification Inventory (TAMI; Beddow, Kettler, & Elliott, 2008) and TAMI Accessibility Rating Matrix (ARM; Beddow, Elliott, & Kettler, 2009) are a set of evaluation tools designed to facilitate a comprehensive analysis of tests and test items for the purpose of enhancing access and meaningful responses from all students.
The TAMI was developed as part of the Consortium for Alternate Assessment Validity and Experimental Studies (CAAVES). The rating component of the TAMI, the ARM, was developed as part of the Consortium for Modified Alternate Assessment Development and Implementation (CMAADI).The ARM consists of 2 rubrics: the Item Analysis rubric and the Overall Analysis rubric. The ARM provides a systematic method for evaluating and modifying test items with a focus on improving their accessibility for all students.
The TAMI ARM has been used to conduct accessibility reviews of items from several states' large-scale assessments to help ensure the tests yield scores from which inferences are equally valid for all test-takers.
By using the TAMI and TAMI ARM, new and existing tests and test items can be improved to enhance testing practices for students.
