A study examined the feasibility of adopting National Occupational Competency Testing Institute (NOCTI) examinations for use by completers of vocational programs in Florida comprehensive high schools. A total of 34 candidates in five occupational areas (architectural drafting, carpentry, plumbing, small engine repair, and welding) at four comprehensive high schools were given NOCTI tests. Scores revealed that the students could have come from a population of journeymen based on their performance tests. However, with the exception of small engine repair, student scores in the related information area appear weak. On four of the performance tests and one of the written exams the average student scores were high enough to meet Florida teacher standards. In programs tested, the average performance score achieved by students in comprehensive high schools on five exams exceeded by a substantial margin the average scores achieved by area vocational technical students. Analysis of student scores suggests that with the exception of the performance exam for carpentry, the other performance exams might be usable. Also, while the written exam for small engine repair seemed appropriate for high school use, all other written exams appeared too comprehensive for vocational preparatory students. (MN)
