She does not have a 403b. At some point the district had a money pension plan that got converted to a 457b so she has just kept contributing to it.
As far as I know the there is no advisory or anything with this account, they are just skimming $155 a month out for having the plan.
If your wife is getting any sort of matching contribution from the school, that would be another reason to stay put.
If she isn't getting matching and the plan will let her rollover the balance to an IRA while she is still an active employee, you likely could reduce the fees or at least get more for what you are paying (i.e. financial planning, investment advice, etc).
You said she is contributing $300 per check. If that is a bi-monthly check, then she is contributing @ $7800 to this plan. IRA contribution limits are $6500 this year (+$1000 if > 50), so she could likely contribute a similar amount to an IRA. However, it won't be deductible if you Modified Adjusted Gross Income is > $136k. A Roth could be a consideration, in that case, but that is limited if your MAGI is > $228k.
I hope that helps. Good luck.
