When someone you love is sentenced in New Hampshire, one of the first questions families ask is where the person will actually be sent, and why. The answer is classification, the process the prison system uses to assign each person a custody level and a facility. New Hampshire uses a distinctive lettered and numbered custody scale that runs from C-1 to C-5, processes everyone through a reception and diagnostic unit at the state's main prison, and makes classification decisions through a board. This guide explains how classification and housing work in New Hampshire, run by the Department of Corrections, from reception through the custody scale and how people move between them, along with how county jail and federal classification differ, written plainly by people who understand the system from the inside.
It starts at the Reception and Diagnostic Unit
Almost no one goes straight to a permanent housing assignment in New Hampshire. After sentencing, all newly committed men are transported to the Reception and Diagnostic Unit at the New Hampshire State Prison for Men in Concord, which serves as the entry point for the whole male system, while women go through reception at the state's women's prison. During reception, which typically lasts about a month, a person is held separately from general population while a multidisciplinary team of staff interviews and tests them, conducts medical, dental, and mental health assessments, and evaluates education and program needs. Based on that assessment, the person is assigned a custody classification and a housing unit. For families, the key thing to understand is that reception is a temporary processing stage of roughly thirty days, and it is worth waiting for the permanent assignment to settle before making visiting plans.
New Hampshire's C-1 to C-5 custody scale
New Hampshire classifies people on a lettered and numbered scale, where the C stands for classification, running from C-1 to C-5. C-1 is the least restrictive, generally work release with halfway house eligibility, C-2 is low or minimum security, C-3 is general population, C-4 is medium security, and C-5 is maximum security, for the highest risk cases. Most newly sentenced people start at C-3, general population, unless they break rules during reception, which can push them higher. A person who has been at the highest level and is working their way back down typically passes through C-4 on the way to general population. The level a person is assigned determines the kind of housing and facility they go to, from the secure units inside the main prison to minimum security housing outside the walls and, at the lowest level, work release. The custody level shapes nearly everything about daily life, so it is one of the most important things for a family to understand.
How the placement decision is made
New Hampshire makes classification decisions through a classification board, which renders decisions on custody grades, housing assignments, special status, work and training assignments, educational opportunities, program placement, and transfers. The board bases its decisions on a data set built during reception and updated over time, including risk assessment, psychological testing, and social, educational, and work histories. Behavior in custody drives movement between levels, with a clean record and program participation opening the door to lower custody and disciplinary problems pushing it higher. A person can request to appear before the board, and there is an administrative process for routine decisions. A person does not get to choose their facility, and because New Hampshire is a small state with a handful of prisons, the question is usually which custody level and which of a few facilities rather than how far from home. The practical reality for families is that the board, the custody level, and conduct over time all shape where a person goes.
Housing types and moving between levels
New Hampshire houses people in a range of settings depending on custody level and needs. Most people live in general population, in cells or units depending on the facility, while those who must be separated for safety or discipline are held in higher custody units, people at risk are placed in protective status, and the main prison includes a secure psychiatric unit and a residential treatment unit for those with mental health needs. People nearing release or classified to the lowest levels may move to minimum security housing or a transitional work center for supervised employment. New Hampshire has no death row, because it repealed the death penalty in 2019, one of the most recent states to do so. Movement between custody levels happens through reclassification by the board, which reviews a person's behavior, time served, and progress and adjusts the level, which can also move a person to a different facility. For most people, steady good conduct lowers the custody level over time and opens the door to minimum security, work release, and reentry. For families, this is the encouraging part: classification is not fixed, and good conduct generally moves a person toward less restrictive settings.
County jail classification is simpler and local
Before a person reaches the state system, and for people serving shorter sentences, New Hampshire's county jails, often called houses of correction, run their own classification. Each county jail does its own intake and assigns housing based on the charge, criminal history, behavior, and safety, separating people by risk and providing protective or medical housing as needed. County jails also hold people awaiting trial, people serving short local sentences, and people who have been sentenced to state custody but are waiting to be transferred to the Department of Corrections. Because each county runs its own jail, the rules, housing, and privileges vary from one county to the next. For families, the main thing to know is that county jail classification is a separate, local process, and the state prison classification described above only begins once a sentenced person is transferred into the Department of Corrections.
How federal classification works
Federal classification, run by the Bureau of Prisons, uses a structured, points based system that applies the same way nationwide. At intake, the Bureau scores each person on factors like the severity of the offense, criminal history, any history of violence or escape, and the length of the sentence, and that score places them in one of several security levels, from minimum security camps, to low and medium security institutions, to high security penitentiaries, plus administrative facilities for special needs such as medical care or pretrial detention. The Bureau then designates the person to a specific facility, ideally within 500 miles of home, though the actual placement depends on bed space, security level, and program or medical needs. New Hampshire has no federal prison within the state, so a person convicted of a federal crime in New Hampshire will be designated to a Bureau of Prisons facility in another state, often far from home. The biggest practical difference from the state system is that the rules are uniform nationwide and a person can be designated anywhere in the country, so families with a federal case should be prepared for an out of state placement.
The bottom line
Classification is what decides where your person lands in New Hampshire, which uses a C-1 to C-5 custody scale, processes everyone through a reception and diagnostic unit at the main prison in Concord, and makes decisions through a classification board. Most people start at C-3, general population, and move up or down based on conduct, with C-5 the most secure and C-1 work release. New Hampshire has no death row. A person does not choose their facility, but because the state is small, the question is usually the custody level rather than distance from home, and steady good conduct lowers the level over time toward minimum security and work release. County jails run a simpler, local classification, and federal cases mean an out of state placement since New Hampshire has no federal prison. The most useful things a family can do are wait out the roughly thirty day reception period, learn the person's custody level and what it allows, and understand that the board reviews classification and it can change. This is general information about how classification works and not legal advice, and because policies change, the department, the Bureau of Prisons, or the specific facility is the right source for current specifics.
