The purpose of this study was to survey supervisors and service providers to determine their perceptions of the skills needed to be an effective supervisor of an early intervention program. Of the 1,166 surveys distributed, 442 service providers and 422 supervisors in six states responded to the survey, resulting in a response rate of 74%. Findings revealed that few differences existed between the two professional groups regarding their perceptions of necessary supervisor competencies. Survey items ranked as the most important had three themes: knowledge of rules and regulations, competence in interpersonal skilb, and awareness of best practice in early intervention. Prior to the passage of P.L. 99-457, there were increases in the personnel shortages at all critical personnel shortages across the counprofessional levels and across disciplines (e.g., try (Meisels, Harbin, Modigliani, & Olson, 1986; paraprofessionals, therapists, teachers, adminSmith & Powers, 1988).

The purpose of this study was to compare the concurrent validity of the Battelle Developmental Inventory (BDI) with the Vineland Adaptive Behavior Scales (Vineland) and the Bayley Scales of Infant Development (Bayley). The sample included 67 children with motor delays and a mean aye of 18.63 months. These children were administered either the Vineland, Bayley, and/or the BDI or some combination of all three. As a replication of McLean, McCormick, Bruder, and Burdy (1987), this study revealed similar flndlnys and Indicated that the BDI possessed moderate to hiyh levels of concurrent validity with appropriate subtests from the Vineland and the Bayley.

The purpose of this investigation was to examine the test-retest reliability of the Bayley Scales of Infant Development (BSID) (Bayley, 1969) with infants in a high-risk follow-up clinic. Eighty at-risk infants participated in this investigation. These infants were given the Mental and Motor Scales of the BSID at 6 and 12 months of age. Test-retest reliability scores of. 71 on the Mental Scale and. 69 on the Motor Scale were obtained.With the passage of PL 99-457, increasing emphasis will be focused on identifying infants and young children who need special services. A myriad of factors should be considered when developing an identification system for handicapped or at-risk infants, including medical, family, and developmental variables. A major interest in determining an identification process is the selection of assessment instruments that consistently indicate the developmental course of the highrisk infant.Currently, the primary focus of infant assessment has shifted from long-term prediction to early identification of children who need early intervention. The purposes of infant assessment are considered to be threefold : (a) to provide a practical method for screening infants in need of further diagnostic study, (b) to provide information regard-
