Health Insurance, Pension, 21 paid vacation days, 9 personal holiday days, and massive amounts of sick leave
Health insurance for teaching assistants is excellent and affordable. Don't expect to start a retirement fund, as the pay is veryy low.
UW - Madison has a competitive vacation time and sick leave accruall
Amazing time off. No way you can use them all up in a year.
Health insurance benefits are excellent, although the State legislature has reduced the State's financial contribution to some extent. Legislative changes have also removed domestic partner benefit coverage from the UW System and other State employers as of 1/1/2018, a change which (in my opinion) will reduce the quality of the UW System over all.
There is nothing much greater about the benefits package. Just the basic compensation for a student part-time job ($10 per hour, 12 hours per week).
Tuition reimbursement is inadequate for a teaching hospital
It has additional eye/dental benefits besides the general benefits, which is about $20/per month. It will cover more situaions.
The insurance is good. It covers most of the necessary parts. Do not have others. The salary is not high, either.
Graduate assistants (and research interns) get good health insurance at low rate ($45.50/month) for 2017. Includes basic dental, for more extensive dental/vision have to purchase separate plan (not sure the rate, but fairly cheap).
