Textual information, 32 tables, and 12 figures are used to describe Alaska high school seniors in this 12th annual survey report. During the fall of the 1988-89 school year, 3,254 seniors attending Alaska public and private high schools responded to the questionnaire sent to a total of 5,910 students for a return rate of 55.1 percent. The questionnaire covered demographic characteristics (sex, race, primary home language, income, etc.); a description of the high school experiences of the student (evaluation of school experiences and identification of possible areas of weakness); a description of the educational experiences of the student in specific target disciplines (foreign languages and computers); the postsecondary plans of the respondent (occupational choices, choice of college, and comparison between seniors planning and seniors not planning postsecondary education); and more detailed representation of those respondents planning to pursue postsecondary education (state of attendance, Alaska attendance, reasons for institutional choice, familiarity with financial aid, and plans to return to Alaska). Appendices contain a copy of the survey form and data tables. (JDD)
