Children are eligible to receive scholarships if their family income does not exceed 400 percent of federal poverty guidelines ($120,000 for a family of four in 2023–24).

EdChoice Expert Feedback

Iowa’s tax-credit scholarship program helps more than twelve thousand students access schools that are the right fit for them, but policymakers could do more to expand educational opportunity. 

Eligibility for the scholarships is limited to 400 percent of the federal poverty line ($120,000 for a family of four in 2023–24). Seven out of ten Iowa students are eligible for a scholarship though less than 10 percent of students statewide actually use a scholarship. (Additionally, Iowa families are eligible for an education savings account program and a very modest tax credit for tuition and textbooks.) 

The average scholarship size is only about $1,500, which is roughly 13 percent of the average expenditure per student at Iowa’s district schools. Tax credits are worth 75 percent of the value of the contributions to scholarship organizations. Only $20 million in tax credits are available annually, which is equivalent to just 0.6 percent of Iowa’s total K–12 revenue.  

To expand access to educational choice, Iowa policymakers should dramatically increase the available tax credits, increase the credit value to 100 percent, and expand eligibility to all students (prioritizing scholarships based on need).  

Iowa’s scholarship program avoids unnecessary and counterproductive regulations.
