This case study explores the impact of peer group supervision (PGS) for counselors delivering Teaching Recovery Techniques (TRT), a group psycho-social program for traumatized adolescents. Interviews were conducted with seven school counselors, from villages near East Jerusalem in occupied Palestine; a skilled supervisor; and an international trainer. A quasi-qualitative analysis was conducted to quantify responses and themes along with a measure of inter-rater reliability. Participants reported that even in a context of military violence, PGS provided a reflective process inclusive of formative, normative and restorative functions. Locally available PGS was viewed as essential within a geographically fragmented context. Counselors' reported PGS led to a trusting environment in contrast to military practices and gender norms. War stressors and lack of Training of Trainers led to low counselor confidence in training others in TRT. PGS and Trainer of Trainers were recommended as core aspects of program delivery and to support training of colleagues.
