Outcome data in school counseling can include which of the following?

Outcome data in school counseling refers to measurable results that demonstrate the effectiveness of the counseling program in achieving specific goals for students. Promotion rates and standardized test scores are clear examples of academic achievement that can be directly influenced by the counseling program. By tracking these metrics, schools can assess how well their counseling services support students' academic progress and overall success. Such data can help identify the impact of counseling on student outcomes, providing valuable information for program evaluation and improvement.

In contrast, while extracurricular participation rates and the number of students in counseling can provide useful information about student engagement and resource utilization, they do not directly measure the impact of counseling on academic outcomes. Additionally, ethnic diversity of the student population is more an indicator of demographics rather than a direct outcome of counseling services. Hence, the most relevant choice regarding outcome data in this context is promotion rates and standardized test scores, as they reflect the end results of the counseling efforts.
