How to determine the timing of measurement for program evaluation?

Cheers.

I am very impressed by your quick reply. Thanks!

Determining the timing of measurement in program evaluation involves careful consideration of various factors. Here are some key steps to help determine the timing of measurement for program evaluation:
1. Clarify program objectives and outcomes: Identify the objectives of the program and the specific outcomes you intend to measure. Consider both short-term and long-term outcomes. Short-term outcomes may be measured during or immediately after program completion, while long-term outcomes may require follow-up measurements over an extended period.
2. Identify relevant time points: Determine the critical time points or milestones in the program where significant changes or impacts are expected to occur. These time points could coincide with key program activities, interventions, or stages.
3. Consider the program duration: Take into account the duration of the program itself. If the program is short-term, it may be feasible to conduct measurements at specific intervals throughout the program's duration. For longer-term programs, consider the appropriate frequency and intervals for measuring outcomes, balancing the need for timely data with practical considerations.
4. Allow for sufficient time for change: Consider the time required for the program's effects to manifest. Some outcomes may take time to develop or become observable.
5. Resource availability and feasibility: Assess the resources available for data collection, including personnel, funding, and logistical support. Consider the feasibility of conducting measurements at different time points, including the costs and efforts involved. Select a measurement schedule that strikes a balance between obtaining meaningful data and resource constraints.
6. Stakeholder preferences: Consider the preferences and expectations of key stakeholders, such as program funders, implementing agencies, or participants. Engage stakeholders in the evaluation planning process to ensure their perspectives are considered when determining the timing of measurements.
