I am currently a cover supervisor and in charge of the Duke of Edinburgh award at an oustanding school. However no matter how hard I try to get a job nothing seems to work. I'm starting to worry that the longer I am at my current job the less chance I will have at starting my nqt year. Is there a specific period of time that would reflect badly on my application as being a cover supervisor? As an employer would 2,4,5 years as a cover supervisor reflect negatively on me as an applicant?
