Our training program is based on a variety of sources and upon our experiences over the past fourteen years. We also make reference to curriculum provided by the International Association for Healthcare Security and Safety (IAHSS) and as of June 2008, Prevention Management of Aggression and Violence (PMAV) obtained through the Canadian Training Institute. Other material has also been reviewed and adapted for use by ESS after review by the management team and Board Members. ESS utilizes Supervisors as an accessible level of management in each area.
