This paper presents some implications concerning career choice obtained from an analysis of the test and survey results for 400,000 high school students. These students were tested by Project TALENT in 1960, were followed up five years later, and were again surveyed in 1970 with selected parts of the TALENT test battery. These papers relate mainly to the increasing realism of choices, especially of the boys; the distinctive patterns of scores for career groups identified five years after graduation; and to the importance of earlier choices of at least the general nature of the career field. The paper reports new findings and relates these to some of the previously reported results. The findings are as follows: the unrealistic and unstable career choices characteristic of high school students throughout the country in 1960 are no longer typical of today's students; later career activities could have been planned on the basis of information available in high school; and if secondary education is to be relevant to student's needs and plans, it is essential that students be assisted in selecting their careers at an earlier time.
