In an attempt made to stu~ the effect of trainee academiornbackground and other related factors in the seoondaryrnschool upon performance ~, ..theT.T.I. and the curr'icularrn implications thereof, corr tion and regression methods,rnquestionnaires, and interviews were used. The study wasrnconducted in o~der to investigate if there were any .rnpro blainsof poor performance and',with this, to'-creaternproblem awareness and to seek solutions as well. Resultsrnhave suggested that there tends to exist a problem of lowrnlevel of performance in the T.T.I. They have also pointedrnout that this performance is an outcome not of the levelrnof qualification of teaohers, or the volume of booksrnavailable in the schools from which the trainees werernrecruited, but of their previous level of academic achievement,rnand more a function of the degree of differentialrnacademic exposure. Outcomes have also indicated that therncurriculum development process has not employed the stepsrnin developing the curriculum as effectively as they shouldrnhave been so as to contribute to a rise of performance torna level that could bringabout a desirable level of competence.rnBased on these outcomes, it is recommended thatrnthe training programme should devise appropriate mechanismsrnthat could be helpful to raise performance levels such asrnremedial classes. It is also recommended that the processrnof curriculum construction should strictly adhere to thernsteps that must be followed in producing the curriculumrnfor better effectiveness with the programme it guides.rnAt last, it is suggested that relative specialization ofrntrainees in some broader areas of specialization (e.g.rnSocial Science, Natural Science) could be taken as arnsolution to problems emanating from the effect of differentialrnacademic exposure. Of course, this is when considerationrnis given to trainee needs. It could be impelementedrnby making use of such attributes of trainees as the alreadyrnrecorded ability, results of pretests, and identifiedrninterests as a basis for streaming into different areasrnor relative specialization.
