Value of experience
Technically, a school can add a discretionary point to the annual increment Rwhere a teacher's performance in the previous school year was excellent having regard to all aspects of their professional duties in particular classroom teachingS. That is what the regulations say. But, trying to convince your head that you are excellent in everything as an NQT, may be difficult. Your best opportunity would have been to have asked for more on the basis of your experience when you were appointed. Of course, the first degree isn't worth anything extra, as all teachers are expected to possess that level of qualification.
