Medical Screening for Outward Bound School  (OBS) Certain Outward Bound School (OBS) programmes require a medical screening prior to participation. Since 2005, we have been providing an efficient and affordable service to teachers co-ordinating their school’s participation.We provide an on-site service at  your  school to facilitate the orderly screening of large numbers of students, followed by a    summary of fitness status to the teacher.  For children with unusual medical conditions, our doctors can liase directly with OBS to discuss the case. Our service supports all OBS participation ranging from a 16-student single afternoon screen to a 500-student multi-day screen, depending on the level of participation of your school.
