32 Miss. Code. R. 21-6-6.3
The IPE must be initiated after eligibility determination by a qualified rehabilitation counselor has occurred. The Agency shall determine whether an individual is eligible for vocational rehabilitation services within a reasonable period of time, not to exceed 60 days after the individual has submitted an application for services. The eligibility determination period may be extended if: (a) exceptional and unforeseen circumstances beyond the control of the Agency preclude the making of the eligibility determination within 60 days and the Agency and the individual agree to a specific extension of time, or (b) if the Agency is exploring an individual's abilities, capabilities, and capacity to perform in work situations through the use of Trial Work Experiences. Such experiences should be of sufficient variety and over a sufficient period of time to determine the eligibility of an individual.
