1II. The three parts of the 1992 National Adult Literacy Survey (test) measured prose, document, and quantitative literacy.
A. Literacy was defined by a national panel of experts to be "Using printed and written information to function in society, to achieve one's goals, and to develop one's knowledge and potential."2
B. "Unlike traditional definitions of literacy, which focused on decoding and comprehension, this definition encompasses a broad range of skills that adults use in accomplishing the many different types of literacy tasks associated with work, home, and community contexts."3
C. Using an everyday format, questions involved things like using a newspaper story to measure prose literacy, using a transportation schedule to measure document literacy, and using a loan advertisement requiring an interest calculation to measure quantitative literacy.
D. Approximately 26,000 people over the age of 15 years participated in the survey.
