Avoid making quick cosmetic changes to your resume just to get back out there, especially if you are switching gears. Your readers will see through it quickly. You’ll need to work harder to persuade them that you are a viable candidate. Consider too, that the potential employer also has a short attention span and is looking for reasons to disqualify you quickly.
Decide which fields you want to work in. As a former English teacher, you may want to work as an editor. If you were an airline stewardess, for example, perhaps you are looking for a job in customer service. As a technical writer, you may want to switch to instructional design.
Get job descriptions for your new desired position. Before writing your career change resume, check some of the postings in such job banks as monster.com. In Canada where I live we have something the NOC guide (National Occupation Classification) which gives detailed descriptions of the roles and competencies required for many jobs. You’ll find similar kinds of information on government websites.
Do a transferable skills inventory. You have been skill building all your life. Whether you know it or not you have 1200 skills plus, according to some experts. Certian core skills transfer well to different types of positions. These include communication, interpersonal, administration, and problem solving skills.
Focus on those skills that will transfer well to your new desired occupation. For example, if you were in IT, and now want to do teaching, then examine your work experience and see if you have done any training. Go into this role in more detail along with any relevant training or volunteer work. De-emphasize or delete the rest.
Consider taking some short courses that are relevant to your new field. Many community colleges offer hands on training that will give you a chance to learn and apply new skills right away in projects and assignments. This counts for relevant experience in your career change resume.
