What type of measurement provides information on the effectiveness of specific interventions regarding target behavior?

Sub-skill mastery measurement (SMM) is focused on assessing specific behaviors or skills to determine how effectively an intervention is working. This type of measurement allows educators and school psychologists to evaluate the impact of targeted interventions on particular sub-skills within a broader domain. By focusing on discrete behaviors, SMM provides clear data that can inform whether an intervention is achieving its goals and can help in making necessary adjustments to optimize student outcomes.

In contrast, general outcome measurement (GOM) looks at overall performance rather than the impact of specific interventions on target behaviors. Standardized testing measures a broader set of skills and often doesn't provide the nuanced feedback needed for assessing individual interventions. Qualitative assessment typically involves subjective analysis, which may not yield the precise data necessary to evaluate the effectiveness of specific interventions directly. Thus, SMM is the most suitable choice for assessing the effectiveness of interventions focused on particular target behaviors.
