In an attempt made to study the effect of trainee academicrnbackground and other related factors in the secondaryrnschool upon performance in the T.T.I. and the curricularrni mplications thereof, correlation and regression methods,rnquestionnaires, and interviews were used. The study wasrnconducted in order to investigate if there were anyrnproblems of 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 teachers, 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 shouldrnha ve been so as to cont ribute to a rise of performance torna level that could bringabout a desirable level of competrnence. Based on these outcomes, it is recommended thatrnthe training programme should devise appropriate mechanismsrnthat c o'uld be he l pful to raise performance l evels such asrnr emedial cla sses . It is also reco n~ended tha t the processrnof curriculum construction should strictly adhere to thernsteps that must be followed in producing the curriculumrnfor better effectiv eness with the programme it guides.rnAt la st , it i s suggested that relative spe cialization ofrntrainees in some broader areas of specialization (e.g .rnSocial Sci ence, Na tura l Science) could be taken as arnsolution to problems emanating f rom the ef fe ct of differentialrnacademic exposure. Of course, this i s when considerationrnis g i ven to trainee n eeds . It could be impelementedrnby making use of such attributes of trainees as the alreadyrnrecorded ab ility , result s of pretests, and id ent i f i edrnint eres ts as a basis for s treaming into different are asrnor r el a tive specia l ization .
