Number/percent of adolescents served or reached by the program

The number of adolescents who have received program services, have participated in program activities, and have been exposed to program mass media messages

The evaluator can subdivide the total number exposed by the type of activity: school-based program, clinical services, youth center activity.  In addition, surveys (if used) can show the percent reached by mass media messages. The evaluation can also classify participants in these activities by relevant characteristics such as: age, gender, marital status, race/ethnicity, socio-eco­nomic status, school matriculation status, employment status, pregnancy history, history of sexually transmitted infections, and contracep­tive use history.

As a percentage, this indicator is calculated as:

(# of adolescents served or exposed to the program/ Total # of adolescents in the intended population) x 100


Program service statistics or comparable data indicat­ing the number and characteristics of adolescents served by the program; responses to survey questions on expo­sure to or participation in program activities. Where feasible, evaluators can collect comparable data on ado­lescents not served or reached by the program to verify that the program is reaching its intended audience and to identify under-served segments of the adolescent population.

Evaluators may want to disaggregate by the following age ranges: 10-14, 15-19, and 20-24.


Program records or surveys of the program‘s intended population/audience In programs that provide differ­ent types of services (e.g., youth centers offering recre­ational, educational, and health services), evaluators should compile service statistics separately for each major type of service or activity.


This indicator measures the volume and characteristics of adolescent clients who participate in program activi­ties or use program services. The exact wording of the indicator will vary by type of program.

Evaluators can readily compile data on the number and characteristics of adolescents that attend program ac­tivities or seek clinical services at fixed sites. To mea­sure the reach of mass media and similar programs, evaluators can survey the intended audience and thus obtain counts or estimates of the percentage of adoles­cents “exposed“ to specific communication programs.

In addition to the number and percent of adolescents in the intended population served or reached by the pro­gram, the evaluator should ascertain if the program reaches key sub-groups of adolescents. For example, health facility-based programs that reach primarily older, married females who have previously been pregnant will likely have a very different population impact than will comparable programs that reach younger, unmarried adolescents of both genders. Similarly, —low-risk“ youth recruited as peer promoters who contact and engage other low-risk youth will likely have a very different population impact than will higher-risk youth recruited to contact other higher-risk youth.  In short, the evalua­tor needs to verify that the program is reaching the sub­groups of interest within the population at large.
