Substitute teachers are essential – and good ones are difficult to find. Over the years, you, as Head, have assembled a key group of talented, reliable substitute teachers. They are the first people called because of their expertise, their teaching skills, and their knowledge of and support for your school. Similarly, your school may be their first choice for work assignments. However, as your programs change or your teachers learn and apply the latest pedagogy, these substitutes may begin to feel out of place in your faculty culture. Consider offering annual orientation and professional development to your core group of substitutes so that they, like your regular faculty members, can maintain excellence in the classroom.
