Dependent Eligibility Verification Project

Project Overview

Iowa State University is committed to offering quality, affordable healthcare plans to our faculty, staff, and their eligible dependents. As part of this commitment, Iowa State verifies the eligibility of all dependents enrolled in Iowa State University's medical, dental, and/or vision plans. Iowa State has partnered with WTW (formerly Willis Towers Watson), a long-time Iowa State benefits partner and consultant, to manage this project. This webpage provides useful information about the project, most of which will be sent directly to employees who have dependents on a medical, dental, and/or vision plan. 


Eligible dependents include: spouse, domestic partner, and dependent children. Dependent children may be covered until December 31 of the year they turn age twenty-six (26). If covering a dependent child over age twenty-six (26), they must be an unmarried, full-time student (student status verification is required).
