Idaho State Statutes - Idaho Attorney Directory

Each person convicted of an
offense against the state, which was committed prior to July 1, 1986, and
confined in a penal or correctional institution for a definite term other than
for life, whose record of conduct shows that he has faithfully observed all
the rules and has not been subject to punishment, is entitled to a deduction
from the term of his sentence beginning with the day on which the sentence
starts to run as follows:
(1) Five (5) days for each month, if the sentence is not less than six
(6) months and not more than one (1) year.
(2) Six (6) days for each month, if the sentence is more than one (1)
year and less than three (3) years.
(3) Seven (7) days for each month, if the sentence is not less than three
(3) years and less than five (5) years.
(4) Eight (8) days for each month if the sentence is not less than five
(5) years and less than ten (10) years.
(5) Ten (10) days for each month, if the sentence is ten (10) years or
more.
When two (2) or more consecutive sentences are served, the basis upon
which the deduction is computed is the aggregate of several sentences.
In addition, those inmates doing an outstanding job, may be awarded
industrial or meritorious goodtime under rules adopted by the state board of
correction, not to exceed five (5) days per month.
Inmates performing exceptionally meritorious or outstanding services under
rules adopted by the state board of correction may be awarded a lump sum of
goodtime. The number of days awarded may not exceed the regulatory maximum.
