PERSI Overview

PERSI is governed by Title 59, Chapter 13, Idaho Statute. Employees become a PERSI member when they work for the District, a PERSI employer. Enrollment in the PERSI Base Plan is automatic. Both the employee and the employer make contributions to PERSI. The employee’s contributions are credited to a personal account, while employer contributions are pooled in a trust fund to cover future benefits for all members.

The PERSI Base Plan is designed to provide pension benefits to career public employees. The longer an employee works for PERSI employers, the greater the Base Plan retirement benefit will be. Although employees may not remain a public employee their entire career, if an employee works for a PERSI employer and earns 60 months of service credit they will be vested to receive a lifetime benefit at retirement. The 60-month vesting period does not have to be with the same PERSI employer. So unless an employee leaves public employment altogether, changing jobs should not affect PERSI membership. With over 800 employers across the state belonging to PERSI, an employee could very well work for a PERSI qualified employer at different points in their career.
