Given the vast range of potential roles and courses in education, you will need to research what is available. The U.S. Department of Education website provides general updates on the field. Also consult your school district and state education department for news on policy and training advice. The National Education Association also has information to get you started on finding courses. Networking is invaluable for grass-roots information; talk to teachers about the key changes to curriculum, legislation and practice. Think about the types of courses that are available. You may have to wait for formal seminars and courses; you can do online or distance training right away.
If you’ve been out of education for a long time, it's important to update yourself on developments in the field, including changes to the curriculum. Going back to book work is helpful. Revisit key texts and policies you've studied previously.
You may need to review and update general work skills such as using information technology. Find out what software local schools use and seek out training in those programs. If you haven’t applied for a job in a long time, courses on resume development and interview techniques might be useful.
Being out of your profession for some time can erode your confidence and leave you out of practice in managing your time, dealing with difficult people and asserting yourself. You also need to set new career goals and work out a plan to reach them. Personal development courses, or even hiring a personal coach who specializes in career skills, will help to renew and strengthen your work skills.
