The purpose of this study is to evaluate the quality of instruction among professionals who implement additional professional support for students with special needs in Slovenia, with a focus on methods for learning to learn. A total of 1863 professionals with various job positions participated in the study. The results revealed that seven groups of professionals most often use methods for achieving standards in different learning subjects. The largest significant differences are in methods for developing social emotional skills, methods for rehabilitation and compensation of disabilities and methods for development of attention and concentration. The results also revealed that subject teachers use most of the methods significantly less than other professionals, which rise concerns about the quality of additional professional support in the group of subject teachers.
