You create relationships that are complex, important, and exciting which can rarely be duplicated in other settings. Teaching is much harder than many initially anticipate. While people are often drawn to the profession for the reasons I described above, they are discouraged when they realize how difficult it is to turn theory into practice. For example, it is hard to teach diverse learners successfully in one classroom without either leaving the most needy behind or neglecting to challenge the most advanced. Very little is currently done in schools to help new teachers deal with the difficulty of the job.
New teachers feel isolated in their classrooms.
They don't have colleagues with whom to collaborate, they often don't have good mentoring, and they don't have ongoing professional development to help them improve their practices. The only tools new teachers have come from themselves - their time and their energy. Whether new teachers burn out because they are tired or because they lack the training and support necessary to be successful, the result is the same. Every year, more good teachers leave the classroom.
