This book provides background information for the Higher Education Act (HEA) reauthorisation process about the direct assistance for education expenses provided through the federal income tax system. Key features of the benefits are explored. Also explored is the relationship of the traditional student aid delivery system with the tax system as a conduit for post-secondary education assistance, identifying specific issues that may be important for congressional consideration during HEA reauthorisation. It also presents newly generated estimates of the value of the credits available to varied eligible recipients. In the absence of actual data, modelling approaches that simulate tax credit values offer perhaps the most promising way to examine the targeting of the education tax credits. Two different modelling approaches are applied in the analysis presented in this book.
