The Prison and Probation Service may release convicts on probation when the person in question, including possible custody, has completed two thirds of the sentence and at least 60 days. If release on probation means that the remaining sentence is less than 14 days, probation can only take place if there are compelling reasons to do so. Convicts who have been sentenced abroad to imprisonment for more than 21 years, and who have been transferred to serve their sentences in Norway, can be released on probation after having been imprisoned for at least 14 years.

The release shall be an integral part of the execution of the sentence, and in each case a specific, individual assessment shall be made of whether release on probation should be granted, cf. below (Refusal of release on probation - the inadmissibility assessment).

Such possible parole at two-thirds applies to sentences of 74 days unconditional imprisonment or more. Convicts with shorter sentences must complete the sentence in full. In very exceptional cases, the convicted person may be released on probation after 60 days of the sentence has been served, even if the remaining sentence is less than 14 days if there are compelling reasons to do so, such as consideration for the convicted person's family or current health / rehabilitation situation.

Even if the conditions for probation are otherwise met, the convicted person shall not be released on probation if the circumstances of the case make probation inadvisable.

In each individual case, a concrete, individual overall assessment must be made of whether the release as a whole appears to be advisable and can therefore be granted. The more of the points below that are partially met, the greater the reason for refusing parole. If the convicted person falls under only one of the points, all the conditions in the point must be met before parole can be refused. It should be considered to obtain information from the police, prosecutors or other agencies if it is considered appropriate and the duty of confidentiality does not prevent it.
