Quick answer
Third-grade prison classification is Spain's open or semi-liberty regime: the inmate leaves prison to work or carry out activities and often sleeps outside the facility, sometimes under electronic monitoring (Article 86.4 of the Prison Regulation). There is no fixed period: classification is individualised and requires favourable progress in treatment, a positive reintegration forecast and satisfaction of the civil liability arising from the offence, especially in economic offences. The prison's Treatment Board drafts the proposal and the central prison authority decides it; a refusal can be appealed before the Prison Supervision Judge and then before the Provincial Court.

Third-grade prison classification is the goal of most inmates: it allows a sentence to be served under a semi-liberty regime, leaving prison to work and often sleeping outside the facility. As criminal defence lawyers, we explain how to apply.
What Third Grade Is
The Spanish prison system is organised in grades. Third grade corresponds to the open regime: the inmate lives under a semi-liberty arrangement, with leave to work or carry out activities, and several modalities — from the ordinary open regime to electronic monitoring under Article 86.4 of the Prison Regulation.
Requirements for Third Grade
- Favourable progress in treatment and a positive individualised forecast of reintegration.
- Satisfaction of the civil liability arising from the offence, especially in serious property, tax or corruption offences.
- For sentences over five years, the court may have set a security period requiring part of the sentence to be served first.
How to Apply and Who Decides
The Treatment Board of the prison drafts the classification proposal, decided by the central authority of the prison administration. Grade is reviewed at least every six months. A strong file — work, training, favourable reports, a life plan — is decisive.
Civil liability is key
In economic offences, failing to show an effort to compensate the victim usually blocks third grade. Planning payment, or a payment commitment, is part of the strategy.
If It Is Refused: the Appeal
A refusal of third grade can be appealed before the Prison Supervision Judge and then before the Provincial Court. A technical defence documenting progress and rebutting unfavourable reports makes the difference.
