It’s not hard to find charter schools in a small town, or even in a major metropolitan area, that fail to meet basic educational standards, according to a report released Thursday by the Institute for College Access & Success.

The institute, which is an affiliate of the George Washington University, found that the schools failed to meet standards in reading, math and science, as well as graduation rates.

The report is the latest to document the failure of charters to meet the standards set by federal regulators, who have been working to expand access to public schools, including charter schools.

Charter schools, which are publicly owned, are designed to help families of all income levels in making ends meet.

But many of the schools are also plagued with financial problems that have made them less attractive to low-income families and those with limited education.

“This report shows that charter schools continue to struggle to meet these standards despite significant federal investment,” said Richard H. Hasen, a professor of education and policy at George Washington and the institute’s executive director.

“This means that, as more of the nation’s poorest families have fewer options, charter schools will continue to suffer in the long term.”

The report said the number of charter schools was down 7 percent from a year ago, with the number in the District dropping from 1,988 to 1,764.

The number of students in charter schools dropped by 12 percent over the same period.

It said the percentage of charter students who graduated from high school or college was down 6 percent from the year before, with only half of those who graduated going on to college.

Teachers, principals and other employees also are more likely to be laid off.

One in five charter schools were shuttered over the past year.

The charter school sector is growing at a rate of 2 percent per year, according the institute, but enrollment has been shrinking for a long time.

Since 2010, charter enrollment has declined more than 13 percent.

In 2015, the Education Department said charter schools had not performed as well on graduation rates as traditional public schools and had also been more likely than traditional public high schools to drop students, resulting in a net loss of graduates.

It also found that students who had been enrolled in charters in previous years were more likely for them to drop out or to drop to the lowest levels of education.

The institute said charter students are not required to be certified by a state-authorized credentialing agency to attend traditional public school, which typically requires a diploma from a public high school.

Instead, charter students can take courses from a variety of private and charter schools and are required to complete courses at their own expense, the institute said.

In the meantime, many charter schools have been shuttering to save money.

At one charter school, a teacher and several students are facing dismissal.

The school has since reopened and will continue with its classes, the school’s administrator, James R. Mazzotti, said.

A spokesman for the Education Secretary, Arne Duncan, said in a statement that the report “reinforces the importance of ensuring that our public schools are open to all students.”

In the District, charter school enrollment has remained flat since the fall of 2014, according, according Education Department data.

There were 4,564 charter schools across the country, according a 2017 report by the Education Trust, an education nonprofit, that analyzed data from the Federal Register.

The report found that charter school students were the largest group of students enrolled in traditional public public schools at 11.6 percent of the students in the district.

Other cities and states are doing a better job of expanding charter schools compared to the District.

New York City opened a pilot program last year that allows students to use their own funds to attend public schools.

It opened more than 10,000 charters this year, with another 30,000 planned.

Some states have expanded charter schools or expanded their number of schools.

Maryland, where charters are permitted, added a total of 2,000 charter schools last year.

Connecticut, where there is a ban on charters, has added more than 700 charter schools since 2016.

States are also creating new types of charter programs.

For instance, New Jersey is opening a pilot school program to offer charter schools to students with special needs and students with disabilities.

In the District of Columbia, schools have begun offering charter schools for students with autism, special needs or disabilities.

In New York, the state has started pilot programs to offer charters for students who are deaf, have a developmental disability, are disabled by a mental illness or have a learning disability.

In Michigan, which has more than 200 charter schools under construction, students enrolled with a disability or a learning disorder can take charters if their school board approves it, the Department of Education said.

And a district in Ohio opened a charter school for students whose parents are financially responsible for the school.

In Louisiana, the Louisiana Department of Elementary and Secondary Education
