Screening for Special Diagnoses (continued)

Problems and Solutions for School Screening

It is important to understand that there is no standard or uniform battery of tests, checklists, or procedures to follow for the identification of most students with disabilities. While there is a basic structure to the identification process, there is considerable variability in how students may come to be identified, including the types of tests used in screening and the processes by which they are referred.

Critics have argued that the procedures used to identify children and youth with special needs have resulted in over- as well as under-identification of students with disabilities. As several studies have shown, a referred child almost always qualifies for special education (Christenson, Ysseldyke, & Algozzine, 1983). Over-identification has been particularly problematic in the area of learning disabilities (Hunt & Marshall, 1994), as approximately half of all students receiving special education services are identified as learning disabled! In contrast, students with behavioral disorders appear to be under-identified, particularly children who are compliant and nonaggressive but suffer from problems such as depression, school phobia, or social isolation (Walker et al., 1990).

To remedy problems of over- and under-identification, educators have begun to institute several changes in the screening and referral process. One approach has involved the development of better screening procedures. For example, Walker and his colleagues (1990) devised a screening process, the Systematic Screening for Behavioral Disorders, that relies on a three-step process. Teachers (1) rank-order students along specified criteria and then (2) use checklists to quantify observations about the three highest-ranked students. Then, (3) other school personnel (for example, school psychologists or counselors) observe children whose behaviors exceed the norm for the teacher's classroom. Referrals are made for further evaluation only after the three-step process is completed.

A second common practice aimed at improving the identification process involves the use of prereferral interventions (Chalfant, 1985). These interventions have been developed to reduce the number of referrals to special education and provide additional help and advice to regular education teachers. Before initiating a referral for testing for special diagnosis, teachers first attempt to deal with a child's learning or behavioral problems by making modifications in the regular classroom. If these modifications fail to address the difficulties the child is experiencing adequately and the teacher believes that special services may be warranted, then the referral process is set into motion. Currently, 34 of 50 states require or recommend some form of prereferral intervention (Sindelar, Griffin, Smith, & Watanabe, 1992).

Two of the more common prereferral intervention approaches include Teacher Assistance Teams, (TATs), and collaborative consultation. Both approaches involve professionals helping regular educators deal with students who have problems in their classroom; however, they differ in an essential way. TATs typically consist of a team of three teachers with the referring teacher as the fourth member. The TAT model provides a forum where teachers meet and brainstorm ideas for teaching or managing a student. In contrast, most collaborative consultation models employ school specialists (resource room teachers, speech-language clinicians) who work directly with the referring teacher to plan, implement, and evaluate instruction for target students in the regular classroom.
