K–12 Education Guide

Charter Schools

Discover the unique approach of charter schools — publicly funded, independently operated, and tailored to meet your child's specific educational needs.

Overview

Understanding Charter Schools

As you consider charter schools for your child, think about their learning preferences, interests, and educational needs. This guide is intended to help you understand what charter schools offer and decide if they might be the right choice for your family.

Charter schools are publicly funded, independently operated schools established by teachers, parents, or community groups under the terms of a charter with a local or state authority. They are designed to offer more educational choices to families and are exempt from some regulations that apply to traditional public schools, fostering innovative teaching practices. Because they remain public schools, they are tuition-free for all students.

Charter schools are held accountable through their charter agreements. Authorizers — typically state or local education agencies — can and do close underperforming charter schools, making accountability a defining feature that distinguishes them from traditional public schools.

School Types

Types of Charter Schools

Charter schools come in several structural forms, each with a distinct operating model and approach to delivering education.

Conversion Charter

An existing public school converts to charter status in order to implement a new or innovative educational model while retaining its existing student community.

Start-Up Charter

A brand-new school founded from scratch by educators, parents, or community organizations with a specific educational vision and pedagogical approach.

Virtual Charter

Delivers instruction entirely or primarily online, offering maximum scheduling flexibility for students who need alternatives to traditional in-person schooling.

Hybrid Charter

Blends traditional in-person classroom instruction with online coursework to create a flexible, personalized learning environment for each student.

Enrollment & Costs

How Enrollment Works

Charter school enrollment follows a structured process that differs from traditional public school enrollment. Here is what families need to know.

Application Process

Parents complete an application form, found on the school's website or by contacting the school directly. Applications are typically submitted during a designated open enrollment window.

Most charter schools have specific open enrollment periods during which applications are accepted. Missing this window may require waiting until the following year.

Lottery System

Because many charter schools receive 2–3 times more applications than available seats, a random lottery is used to select students. The lottery process is designed to give all applicants an equal chance regardless of academic background or address.

Some schools offer priority to siblings of enrolled students, children of staff, or students in the local attendance zone.

Costs & Fees

Charter schools are tuition-free as publicly funded institutions. However, families may pay for specific extracurricular activities, school uniforms, supplies, or optional programs.

Some schools organize fundraising events to supplement state funding. No family should be turned away due to inability to contribute.

Stanford CREDO Research Finding
The Stanford Center for Research on Education Outcomes (CREDO) found that charter schools in urban areas show statistically stronger academic gains for low-income students, Black students, and Hispanic students compared to their traditional public school peers. Urban charter school students gained an additional 40 days of learning in math and 28 days in reading per year on average.
