A study provided accurate and reliable norms that reflected the reading and math performance levels of Iowa's youth and adults engaged in work force preparation and employment training for basic skills. The study population included 819 participants from the Job Training Partnership Act (JTPA) and Iowa's Job Opportunities and Basic Skills programs (PROMISE JOBS) from 11 community colleges. Participants completed a background information sheet and were assessed with CASAS (Comprehensive Adult Student Assessment System) Employability Competency System Appraisal Form 130 or Form 400. Results were reported on a common, five-level scale, ranging from A (Pre-Literacy) to E (Advanced Adult Secondary). The largest percentage of participants scored in Level D or E in reading. The highest percentage scored Level C in math. JTPA participants scored higher in math and lower in reading. The mean reading score for females was nearly four points higher. The mean reading score of those 18 and younger was lower than that of all other age groups except those aged 50 or older. The mean math scores of those 19-25 were higher than those 18 and younger and those 40-49. In general, a greater percentage of the participants who had completed more years of school scored higher in reading and math. Study results could be used in educational achievement reporting, measurement of progress toward benchmarks, and program planning, counseling, and referral.
