I currently work for SWD’s Tuen Mun Children and Juvenile Home (TMCJH). Would it be possible for me to participate in the assessment of the services offered by our institution?

Not to worry.

I see. I really appreciate your response.

In fact, external evaluators are frequently used to assess programs, which may help to ensure dependability, objectivity, and neutrality. However, these days internal evaluators are in demand because they can help an organization learn from and grow as a result of program evaluation findings. Therefore, "Yes" is the only possible response.
