Which type of evaluation is generally accepted for assessing the achievements and/or outcomes of a program?

Using summative evaluation is the most accepted approach for assessing the achievements and outcomes of a program. This type of evaluation occurs after a program has completed its course of action, allowing evaluators to determine the overall effectiveness and outcomes achieved relative to the initial goals and objectives established at the outset.

Summative evaluation looks at the extent of success concerning intended outcomes, providing insights into what was learned and how successful the program was in meeting its objectives. It is typically used to inform decisions about continuation or scaling of programs and can be essential for stakeholders who need to assess the return on investment or impact of the program.

In contrast, formative evaluation is focused on the process of the program while it is ongoing, allowing for adjustments and improvements rather than measuring final outcomes. Diagnostic evaluation is aimed at identifying specific issues or problems within a program, and progressive evaluation involves ongoing assessments throughout a program's development. These evaluations do not typically provide a comprehensive assessment of the program's outcomes in the same way that summative evaluation does.
