What age range does YALSA focus on for its services?

The correct choice highlights that YALSA, which stands for the Young Adult Library Services Association, specifically targets individuals in the age range of 12 to 18 years. This age group is critical as it encompasses the developmental stage of adolescence, where young people are seeking independence and forming their identities. YALSA's focus on this demographic allows for the development of resources, programming, and services that cater specifically to the interests and needs of teenagers, encouraging their engagement with literature and information.

While younger age groups like 5-10 years or 6-12 years are certainly important in educational contexts, they fall outside the primary focus of YALSA. The association aims to address the unique challenges and preferences that come with the teenage years, such as navigating social issues, personal development, and preparation for higher education or employment. The all-ages option does not reflect YALSA's specific mission; rather, it emphasizes their commitment to meeting the needs of young adults during a dynamic time in their lives.
