The purpose of this Request for Proposal (RFP) is to solicit written proposals from parties interested in providing services for the development, implementation, and evaluation of a promotional examination system (herein referred to as PES). The PES will be exclusively for the Hillsborough County Sheriff's Office. It is the intent of the Hillsborough County Sheriff's Office to utilize the PES as part of the organization’s established promotional process for the ranks of corporal, ser-geant, and lieutenant within the law enforcement and detention services divisions. The PES must have: reliable and valid assessment instruments that incorporate standardized testing methodolo-gies and procedures; compatibility with existing Hillsborough County Sheriff's Office software and management information systems; and sufficient data banks of available questions in a ratio at a minimum of 3 to 1 (three alternate test questions for every one question asked on each sepa-rate examination).
