An example:
If an intervention that is designed to reduce dropout rates by increasing engagement with school is delivered to some at-risk children but not others within a given school, it is possible that the children not receiving the intervention will also have their engagement with school increased as a result of the increased engagement of their peers.

Could you perhaps assist me in getting some information about the community service orders (CSO) program verified? According to what I’ve heard, a court may issue a CSO order requiring a person who has reached the age of 14 or older and has been found guilty of a crime carrying a sentence of imprisonment to perform unpaid work for a number of hours up to 240 hours per month while being supervised by a probation officer. Can I refer to those as CSO scheme activities?

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
