Pinpointing particular groups continued as part of the recruitment process for both the community and institutions. It was deemed particularly important to recruit aboriginal candidates due to the disproportionate number of aboriginal offenders in the correctional system. Greater success was experienced in recruiting aboriginal individuals to the community, compared to institutions. Recruitment of women to work in prisons also remained a challenge. The old model of recruitment, hiring and in-service training allowed the Branch to make decisions regarding community postings of new recruits. In some instances, offices were forced to operate with vacancies until new employees completed basic training. Most recruits were hired on provincial postings and only allowed to state their preference of work location. The Branch, however, could place these recruits anywhere in the province for two years. This allowed the Branch to fill remote or northern vacancies. Por some new probation officers, placements outside of the Lower Mainland caused complaints—at least until they became established in their new community. This provincial pool and Branch placement resulted in many probation officers applying to relocate after completion of their two years. Relocation, including attendance at job interviews, housing searches and moving expenses were all accomplished at Branch expense. The ERP attempted to resolve this situation by allowing new graduates to apply for vacancies in any location. Unfortunately, vacancies in many northern locations went unfilled. Students received their ERP training in the Lower Mainland and chose to remain there, instead of applying for positions elsewhere. Challenge exams A challenge exam was developed to accommodate individuals with experience and training in corrections or a related field. A student who achieved a mark of at least 80% on a Challenge exam could be exempted from all or part of the program. Challenge exams wete viewed as maintaining high standards of training and competency for a position while providing credit for training and experience. Eligible candidates for a challenge exam included individuals who: a Worked as a security officer/correctional officer or probation officer for the Branch; a Were out of service for more than two years; or «» Worked as a full-time correctional officer or probation officer in another jurisdiction. Specialized training Changes to offender populations during the 1990s prompted specialized training for probation officers and correctional officers. Staff required additional training to deal effectively with sex offenders, spousal assault offenders and the mentally disordered. The most comprehensive training developed for sex offenders. Although basic training provided information about this offender group, it was not adequate to meet standards for supervision of sex offenders in the community. In 1990, the Justice Institute offered the first sex offender management training course for probation and institutional staff. This was expanded to a certificate program in 1993-94, In response to investigations arising from the Perrault and Gamache cases, sex offender 224 Corrections in British Columbia
