Hi df
Depending upon the level of your surplus income remaining after taking account of household and living expenses, with some provision for contingencies, it is quite possible that an IVA may be a solution for you.
As the other posters have stated, your wife's job as a teacher would not be affected - I have many teachers in my own portfolion who are comfortably paying into their IVA's with no employer problems.
To make an IVA viable with £60,000 of debt, you will need to pay a minimum of £390 per month - but obviously this will increase if your income can support higher payments.
See my blog for tips on selecting an insolvency practitioner and questions to ask to ensure that you are being properly advised,
Good luck in your search.
