Not getting into the middle of this argument but the last sentence in this quote is not correct. My youngest works in a district where getting a master's did not increase the income. Fellow teacher is getting her doctorate and will get no increase from that either.Indiana passed a new starting salary last year of $40k for starting teachers. Want more pay? Get your masters or enough credits to be a masters equivalent. Cost us $10k out of pocket for an $11k increase in pay. That cost was covered after her first year. That will vary by district but it will be an increase in any district.
Again, not entering into a right or wrong scenario just stating the facts as I know them in this situation.
