学校心理学家经常努力评估和干预由于学术和/或行为问题而被转介的学生。这些孩子经常给学校工作人员带来重大挑战。使用问题解决模型，经常要求学校心理学家担任顾问，以帮助学校为面临危险或已确定残疾的学生制定，实施和评估课程。有效地提供学校心理服务需要具备适应性的知识和能力，功能评估，功能分析以及针对情绪/行为领域中的困难的干预措施。同样，学校心理学家需要了解整个系统的变更过程，以制定预防计划，这些计划可能会影响学校和学校系统的大规模变更。
School psychologists frequently work to assess and intervene with students who have been referred because of academic and/or behavior problems. These children often present significant challenges to school personnel. Using a problem-solving model, school psychologists frequently are called upon to serve as consultants to help schools develop, implement, and evaluate programs for students who are either at-risk for or have identified disabilities. Knowledge and competencies in the adaptation of instruction, functional assessment, functional analysis, and interventions for difficulties in emotional/behavior domains, are required for effective delivery of school psychological services. Likewise, school psychologists need knowledge of system wide change processes to develop prevention programs that are likely to effect broad scale change in schools and school systems.
