题型:完形填空
American public education has changed in recent years. One change is that increasing numbers of American parents and teachers are starting independent public schools called charter schools.
In 1991, there were no charter schools in the Unite States. Today, more than 2300 charter schools operate in 34 states and the District of Columbia. 575000 students attend these schools. The students are from 5 years of age through 18 or older.
A charter school is created by groups of parents, teachers and community members. It is similar in some ways to a traditional public school. It receives tax money to operate a number of students. The charter school must prove to local or state governments that its students are learning. These governments provide the school with the agreement, or charter that permits it to operate.
Unlike a traditional public school, however, the charter school does not have to obey most laws governing public schools. Local, state or federal governments cannot tell it what to teach.
Each school can choose its own goals and decide the ways it wants to reach those goals. Class sizes are usually smaller than in many traditional public schools. Many students and parents say teachers in charter schools can be more creative.
However, state education agencies, local education-governing committees and unions often oppose charter schools. They say these schools may receive money badly needed by traditional public schools. Experts say some charter schools are doing well while others are struggling.
Congress provided 200 million dollars for establishing charter schools in the 2006 federal budget. But, often the schools say they lack enough money for programs. Many also lack needed space. District officials say they have provided 14 former school buildings for charter education. Yet charter school supporters say officials should try harder to find more space.
