Once you've established a client's overall needs, set clear goals at each counseling session. For instance, if you counsel people on how to manage personal finances, you might set a savings goal (including amount to be saved and deadline for accumulating the funds). Goals can also be set in psychological counseling.
Monitor the client's progress each time you meet with him or her, and once the goals are met, set up a final evaluation meeting.
Prepare a questionnaire that asks for the opinions of the client regarding your counseling service. In addition to basic questions about the effectiveness of your approach, ask if the client achieved his or her goals as planned. When formatting your questionnaire, use a Likert scale to aid in measuring the responses. Using this tool, you would ask the respondent to rate your services on a scale from one to five (strongly disagree, disagree, neither agree nor disagree, agree and strongly agree).
Compile the results of your final evaluation survey to measure the overall success of your counseling service. Add up and average the responses. Decide on an average that you consider "successful" for your service, such as 3.5 or higher out of five.
