Current national trends regarding the availability and use of information and assessment resources in one-stop centers for employment and related social services were examined in a study of one-stop centers that were nominated for exemplary practice or for fully implementing their state's implementation plan. The sample of 39 consisted of 3 one-stop centers from 13 of the 16 states that had received federal funding for initiation of one-stop centers as of August 1996. Of the 39 surveys mailed, 27 (69%) were returned and deemed usable. The responses provided at least partial evidence that some one-stop principles have been put into practice at exemplary or fully operational one-stop centers. Customers appeared to have access to a range of one-stop services via a variety of service delivery modes. Some evidence of service integration among collaborating organizations was also found. The study's six recommendations included utilizing information professionals in the delivery of information services and increasing the use of written plans and group interventions where possible. (Twenty-one tables/figures are included. The bibliography lists 16 references. Appendixes constituting approximately 60% of the document contain the following: letter describing the study; form for nominating one-stop centers; letter explaining the study; and survey instrument.)
