This annual publication of "The ABCs of School Choice" is a comprehensive, data-rich guide to every private school choice program in America. This publication outlines how each program works, whom it serves, and offers feedback on how it could be changed to help even more families in a particular state. Programs are grouped alphabetically by state and by program type: education savings accounts (ESAs), school vouchers, tax-credit scholarships, and individual tax credits and deductions. New to this year's edition is information about state-based 529 savings accounts, which are privately funded by families for future educational expenses. Following a preface by Robert C. Enlow, the President and CEO of EdChoice, contents of this report include: (1) Types of Private School Choice; (2) Other Types of School Choice; (3) School Choice Illustrated; (4) State Index; (5) Education Savings Account Programs; (6) School Voucher Programs; (7) Tax-Credit Scholarship Programs; (8) Individual Tax Credit and Deduction Programs; (9) 529 Savings Accounts; (10) Rules and Regulations; (11) Legal History; (12) Data Sources for Program Profiles; and (13) Methodology and Data Sources for Eligibility.
