The Alliance for Justice is a nonprofit in the U.S. that maintains a free community organizing web site which includes Resources for Evaluating Community Organizing(RECO). Although these resources are about community organizing in the U.S., they may be of interest to people evaluating organizing in Haiti. Evaluating organizing can be tricky to think about at first as organizing operates in a very fluid environment where goals often shift and by definition often missed (i.e., if it was easy to win a policy change, you would not need organizing), so these may be worth a look.
Note: while RECO nicely summarizes and organizes the resources it tracks, some of them are from journals; thus, you may have to track a resource down at the library or contact the authors (many resources are directly linked, however).
If people have documents related to evaluating organizing in Haiti, please post in the comments or email to me (see the top post of this site for contact info).
