I've personally experienced the results of this organization in...
as evidenced by the improvement in the students' writing abilities (e-mails) throughout the school year.
Would you volunteer for this group again?
For the time you spent, how much of an impact did you feel your work or activity had?
Did the organization use your time wisely?
Would you recommend this group to a friend?
When was your last experience with this nonprofit?
What one change could this group make that would improve your volunteer experience?
Perhaps allowing the volunteer to be a penpal to more than one student at a time if they wanted to.
Did your volunteer experience have an effect on you? (teaching you a new skill, or introducing new friends, etc.)
I have learned to look at books for young readers through the eyes of an adult, and appreciate the efforts of story-telling to guide and influence young lives.
How did this volunteer experience make you feel?
Like I had a positive impact on a child's life.
