S.D. Codified Laws § 24-15A-35
At least thirty days prior to an inmate's initial parole date, the warden shall notify the board in writing of the inmate's substantive compliance or noncompliance with the inmate's individual program directive. If an award of earned discharge credit moves an inmate's initial parole date to within thirty days, the compliance report shall be completed no later than seven calendar days from the date of the application of the credits. If there is insufficient information for the warden to determine substantive compliance or noncompliance, the warden shall report a finding of undetermined compliance to the board. The warden shall also notify the inmate in writing of the warden's report of substantive compliance, noncompliance, or undetermined compliance. At least thirty days prior to an inmate's subsequent, discretionary parole hearing, the warden shall submit to the board an updated report of the inmate's conduct and progress since the last hearing.
