There are many different schooling options, but not all educational choice programs are created equal. Public charter schools and public-to-public transfers, for example, have provided options within the traditional system, but those programs leave many schooling types off-limits for families. EdChoice's goal as the nation's oldest school choice organization is to highlight and promote the programs that create the most pathways for students to lead successful lives, focusing on five types of programs: (1) education savings accounts (ESAs); (2) tax-credit ESAs; (3) vouchers; (4) tax-credit scholarships programs; and (5) refundable tax credits. Individual tax credits, deductions, and 529 savings accounts are also highlighted. These programs are more limited and tend to provide minimal financial assistance to families. This guide introduces the fundamentals of school choice and answers some basic questions about why and how these programs work. This guide is a supplement to "The ABCs of School Choice" (ED628554).
