New employees often learn an organization's unwritten rules-the ''rope
s'' through one-on-one relationships with workplace colleagues or ment
ors. Increasingly, organizations are implementing mentoring programs t
o foster supportive work relationships-and evaluators are being called
on to assess them. This paper presents a systematic literature review
of mentoring-type program evaluations and reveals wide gaps in what p
ublished studies report. The complex and long-term nature of mentoring
programs presents unique challenges to evaluators. To meet these chal
lenges we suggest an evaluation model that attends to local audience n
eeds and addresses four evaluation stages: (I) context evaluation, for
assessing needs, objectives and organizational support; (2) design ev
aluation, to assess mentor and protege characteristics, the process fo
r pairing the mentor and protege, the program duration, activities and
recognition/rewards for participants; (3) implementation stage evalua
tion, to monitor activities, feedback and revisions; and (4) product e
valuation, to assess systematically the planned and unplanned outcomes
that consist of program reactions, learning, behavior change, and imp
act.
