The “Toolkit Project”: Introduction

  • Elizabeth Halper
  • Thomas Allen
  • Donna A. Morere


This chapter presents the rational for the establishment of the VL2 Psychometric Toolkit, beginning with a brief history of psychometric testing with deaf individuals and the complexities of using psychometric instruments with this population. The chapter explains the goal of developing a set of achievement, cognitive, and language instruments which could be administered to a sample of deaf individuals as a set, rather than piecemeal, allowing for investigation of relationships among the areas of skill and functioning. Legal and ethical reasons that such investigations are need are reviewed, as is the unique nature of the relationship between literacy and cognitive functioning in this population. The cognitive and achievement constructs and the assessments used to evaluate them are introduced. This chapter functions as a brief introduction to the overall VL2 Psychometric Toolkit Project and its goal of providing information for a wide range of consumers, including researchers, clinicians, and students in many fields, concerning cognitive functioning, learning, and academic achievement, and the interactions among these parameters, in signing deaf individuals.
