School counselling is developing rapidly in many countries around the World. As with any practice in a secondary setting, challenges and special issues are often identified, discussed, and managed. These can be categorized into four distinct domains: 1) Internal challenges, which include issues related to clientele groups, teachers' attitudes towards counselling, and students' willingness to seek counseling; 2) External challenges, which refer to social-economic changes beyond the school. These include popular culture, globalization and societal trends of more families and students moving across borders; 3) Systems challenges, which are those within the guidance programmes implemented by ministries, schools or counselling bodies. These issues may reside in the guidelines for practice in schools, referral procedures, and resource planning; 4) Personal challenges, which relate to the needs as well as the skills of the counsellor. Some examples here are training, supervision, and attitudes towards school systems. The four domains and interactions among them are discussed in this paper.
