An assessment of service gaps is meant to give an indication of the types of services that are needed the most at the particular point of time in which the assessment is being conducted (www.ncstac.org). A scale measuring the availability, accessibility, provider choice and cultural responsiveness of services, rated on a scale from 0-no availability/non-existent, to 3-outstanding and responsive is provided by the National Consumer Supporter Technical Assistance Center. The scale also assesses the availability of other services in the community such as support groups, education and employment services that may be of interest to the practitioner.
