The Teacher Alert System was designed in Alberta, Canada, for classroom teachers and school personnel concerned about the needs of "at risk" students. The guide can assist in the identification, assessment, and intervention process for children who have special needs. The student's problems may be related to learning, emotions, or physical problems. Such students deviate in some way from what is expected from the school, their peers, and often themselves. Part 1, Family and Welfare Issues, looks at problems the student may be having at home or in the neighborhood, realizing that the cause of the student's problem may not be related to the school or academic program. Part 2, Classroom Environment Factors, examines whether the physical attributes of the school and the classroom, including the stressors in the teacher's life, are conducive to the student's learning. Part 3, Physical/Sensory Disorders, includes health problems, physical disorders, and sensory disorders. Students may be physically incapable at the moment of complying with the demands of the classroom. Part 4, Developmental and Learning Disorders, discusses some of the more subtle disabilities and learning problems. Part 5, Temperament and Behavior Disorders, looks at behaviors that interfere with attention and being goal oriented. These students may need altered expectations, task demands, pressure, or an environment where there is more appropriate stimulation. Issues of "at risk" students, intervention strategies, and use of school centered assessment materials are discussed. (LLL)
