Inpatient treatment is generally a 28-day stay at a treatment facility where clients are not permitted to leave the grounds at any time until they discharge.  Long-term treatment, or Extended Residential Care (ERC), is an elongated, less-restrictive version of an inpatient program.  At the ERC level, clients are able to leave the grounds – in fact, they are encouraged to do so in order to seek/obtain employment, work/volunteer, engage in 12-step peer support meetings, etc.  There is a nightly curfew, and certain therapeutic activities are scheduled into the daily and weekly structure of this level.
