     Most American students go to traditional public schools. There are about 88 000 public schools all over

the US. Some students attend about 3 000 independent public schools called charter schools.

     Charter schools are self-governing. Private companies operate some charter schools. They are similar in

some ways to traditional public schools. They receive tax money just as other public schools do. Charter

schools must prove to local or state governments that their students are learning. These governments provide

the schools with the agreement called a charter that permits them to operate.

     Charter schools are different because they do not have to obey most laws governing traditional public

schools. Local, state or federal governments cannot tell them what to teach. Each school can choose its own

goals and decide the ways it wants to reach them. Class size is usually smaller than in traditional public schools.

     The Bush Administration strongly supports charter schools as a way to re-organize public schools that are

failing to educate students. But some education agencies and unions oppose charter schools. One teachers'

union has just made public the results of the first national study comparing the progress of students in traditional

schools and charter schools.

     The American Federation of Teachers criticized the government's delay in releasing the results of the study,

which is called the National Assessment of Educational Progress. Union education experts say the study shows

that charter school students performed worse on math and reading tests than students in regular public schools. 

     Some experts say the study is not a fair look at charter schools because students in those schools have more

problems than students in traditional schools. Other education experts say the study results should make charter

school officials demand improved student progress.
