Vouchers are documents that provide a holder with a specific value or discount, often used in transactions. They can be issued by businesses, governments, or organizations and are typically redeemable for goods, services, or cash. Vouchers can come in various forms, such as gift cards, discount coupons, or travel certificates. In education, vouchers are used to give families the option to use public funding for private school tuition. This system allows parents to choose schools that best fit their children's needs, promoting competition among educational institutions. Vouchers aim to enhance educational opportunities and improve overall quality.
