Over a decade ago, the U.S. Congress authorized the establishment of the 21st Century Community Learning Centers (CCLC) programs to open schools and public facilities for broader use by the communities. Such centers often offer a wide range of educational and recreational activities to adults residing in the communities to enhance professional knowledge, skills, career development, health and fitness, and quality of leisure. Few studies have investigated the content and quality of activities offered by the 21st CCLC programs. This study was intended to fill the void by examining activity preference, program offerings, attendance level, and satisfaction of adult participants, as well as the sequential relationships between these four variables. Based on a review of literature, a survey form was designed to assess program activities in 12 categories (i.e., arts, career orientation, personal counseling, cultural and social activities, personal development, health and nutrition, mathematics, reading and literacy, science, community service, sport and recreation, and technology). Each activity was phrased into four questions: (a) “Do you prefer this activity in the program?”; (b) “was this activity offered by the program?”; (c) “How often did you attend this activity offered by the program?”; and (d) “How satisfied were you with this activity offered by program?”. A total of 314 parents from 43 21st CCLC programs responded to the survey during an annual evaluation. Adult program participants generally preferred all program offerings. Of them, 80% or more preferred six of the 12 activities: arts, cultural activities, health/nutrition, reading, sport and recreation, and technology. A majority of programs (90%) provided reading and literacy activity; whereas, other activities were usually provided by 50 to 70% of programs. Conducting one-sample t-tests, mean program attendance scores were all significantly greater than 3.0 on a 5-point Likert scale (p < .05), with reading, sport/recreation, health and nutrition, and technology activities being the most attended activities. Overall, adult participants were satisfied with program offerings, with all mean satisfaction scores significantly greater than 4.0 on a Likert 5-point scale (p < .05). Hierarchical regression analyses revealed that significant (p < .05) sequential relationships existed among activity preference, offering, attendance, and satisfaction, with 20-50% variance explained. The findings indicated that the community programs should prioritize reading, sport/recreation, health and nutrition, cultural, arts, and technology activities when formulating curriculum and schedule. Satisfying preferences of adult program participants was more likely to be transferred into high program attendance and perceived quality.Keyword(s): community-based programs, recreation
