To evaluate the TANF program, the evaluator will collect several types of data. First, the evaluator will collect demographical data from the target population. Specifically, the evaluator will focus on the gender and age of the participants. Second, the evaluator will collect information on how the program has impacted the lives of the target population. Third, the evaluator will collect data on the views of the participants on how well the program is implemented. These types of data will help fulfill the purpose of the evaluation which is to determine the effectiveness of the program.

The evaluator will use primary data sources for data collection. This means that the evaluator will rely on information from end-users and those responsible for implementing the program. This is the best option because the collected data will be customized to the evaluation needs. Two data collecting techniques should be utilized. These are interviews and questionnaires (Posavac, 2011). These techniques will help collect data that is richer and with a deeper insight into the program under evaluation. Also, these techniques are easier to apply and cost-effective.

The best sampling technique for the proposed evaluation would be purposive sampling. Through this technique, the evaluator will be able to select participants who can provide thorough and detailed data about the program under evaluation (Royse et al., 2016). Random sampling would also be effective now that many people are affected by the program becoming eligible participants.  Content analysis will be used on analysing the collected data. It is among the best analysis techniques for analyzing qualitative data. Through this technique, the evaluator will find meaning from participants’ responses and then make inferences about these responses.
