Six months into a measles-rubella vaccination campaign in a district, the programme officer reviews vaccine wastage rates, session attendance and cold chain logs, identifies gaps, and modifies micro-plans before the campaign ends. This type of evaluation is best termed:
- A Summative evaluation
- B Impact evaluation
- C Formative evaluation ✓
- D Financial audit
Correct answer: C. Formative evaluation
Explanation
Formative evaluation is carried out during the development or implementation of a programme to improve its performance, exactly as done here with mid-course correction of micro-plans. Summative evaluation judges overall worth after completion, impact evaluation measures long-term effects on health status, and a financial audit examines accounts only. The timing, mid-programme, and purpose, improvement, decide the key.
