A halfway house is an institution that allows people with physical, mental, and emotional disabilities, or those with criminal backgrounds, to learn (or relearn) the necessary skills to re-integrate into society. As well as serving as a residence, halfway houses provide social, medical, psychiatric, educational, and other similar services.
Halfway houses in the US generally fall into one of two models. In one model upon admission, a patient is classified as to the type of disability, ability to reintegrate into society, and expected time frame for doing so. They may be placed into an open bay same-sex dormitory similar to that found in military basic training with fifty or a hundred similar residents in a gymnasium-type setting all going through the same thing at the same time. As the patient is able to increase his skill level and decrease his dependency on support services, the dorm members become fewer to the point where, at the final stage before being able to get their own apartment, the patient may have only one or two roommates.
Another model reverses this. New patients are admitted in individual rooms providing one-to-one services and programming. As they become more independent, the dorms become bigger so that by the time the patient leaves, they are living in the 50-to-100 man dorm described above.
The same two models are used for convicted criminals to begin the process of reintegration with society, while still providing monitoring and support; this is generally believed to reduce the risk of recidivism or relapse when compared to a release directly into society. Halfway houses are meant for reintegration of persons who have been recently released from jail or a mental institution.
There are several different types of halfway houses. Some are state sponsored, while others (mainly addiction recovery homes and mental illness homes) are run by "for profit" entities. In criminology the purpose of a halfway house is generally considered to be that of allowing people to begin the process of reintegration with society, while still providing monitoring and support. This type of living arrangement is often believed to reduce the risk of recidivism or relapse when compared to a straight release directly into society.
Some halfway houses are meant solely for reintegration of persons who have been recently released from prison or jail, others are meant for people with chronic mental health disorders, and others are for people with substance abuse issues, generally called sober living houses. The state-placement of ex-criminal offenders to a "halfway house" after a prison sentence may either be decided upon as part of the judge's sentence or by a prison official's recommendation. A direct sentence to a halfway house can be decided upon by a judge or prosecutor in lieu of prison time.
