The purpose of this study was to examine the accrual state and difficulties and issues of classes on disabilities, and examine the elements related to the difficulties and issues. We conducted a questionnaire survey toward teachers working in public elementary schools. As a result of Categorical Principal Components Analysis( CATPCA), three components were extracted as difficulties and issues:[ 1. Difficulties and issues in processes of carrying out the classes][ 2. Difficulties and issues in prerequisite knowledge][ 3. Difficulties and issues on human environment and time]. As a result of further analysis, nonparametric tests, these possibilities were revealed:[ 1. Difficulties and issues in processes of carrying out the classes] may be reduced by participating in workshops about teaching methods of the classes. [2. Difficulties and issues in prerequisite knowledge] may increase by practicing classes with reading materials, but, decrease because of “plans over six grades” with regard to the classes.[ 3. Difficulties and issues on human environment and time] may not be difficult to teachers who conduct the classes participating people with disabilities, while they may be significant to teachers who conduct the classes about LD/ADHD. For these results, in order to reduce these difficulties and issues, we should put the following into practice:( 1) Enhancing workshops focusing on the teaching methods of the classes,( 2) Working on the classes schoolwide planning and conducting, taking into account the description in the textbooks,( 3) Increasing opportunities of learning and workshops of the teacher training course or in-service stage, and accumulating practical examples or reports of the classes relating to disabilities.
