California's Statewide Longitudinal Study (SLS) of community college students reveals that student services are needed and appear to be effective. Evidence supporting this contention were obtained from a special run of data from third-year interviews with 4,120 of the original sample of 6,490 students. These data indicate that: (1) the level of use of student services, though low, is generally meeting or surpassing expressed need; (2) the percentage of students using specific services by their third year ranged from 40.5% for counseling to 1.9% for women's centers; (3) while only 4% of the students expressed a need for tutorial services in their first year, over 20% had used the service by their third year; (4) 40% of the respondents expressed a need for career planning assistance in their first year; however, only 8.9% had used the service by their third year; (5) over 13% of the students reported using financial aid by their third year, though a rather high proportion were dissatisfied with the experience; and (6) a low proportion of students made use of job placement services. SLS implications include the following: assessment of need for student services should go beyond self-assessment; career planning services should be better publicized and more available; and additional research and development activities should address financial aid, job placement and development, re-entry students, and the service needs of handicapped, nontraditional, and Limited English Speaking students.
