As of the 2000-2001 school year, there were 93,273 public elementary and secondary schools and as of 1999-2000 there were 27,223 private elementary and secondary schools. As of January 2004, there were 2,996 charter schools.
2. How do U.S. students fare on national assessments?
According to the most recent NAEP assessments, only 31 percent of 4th graders are proficient in reading, while 32 percent are proficient in mathematics, 29 percent in science, and 18 percent in American history. Low-income students did half as well. In fact, over half of poor fourth graders failed to show even a basic level of knowledge in reading, science, or history. 
For state-level NAEP achievement data, see NAEP's "State Profiles" page.
Seventy percent of public school students graduate on time, and less than half of these students are qualified to attend four-year colleges or universities. Roughly half of black and Hispanic students graduate on time.  Twenty-six percent of Americans have a bachelor’s or higher degree. Women earn more associate’s, bachelor’s, and master’s degrees and almost half of professional and doctorate degrees.
Over the past 30 years, average per-pupil expenditures for public, elementary, and secondary schools have nearly doubled, rising from $3,931 in 1971-1972 to $7,524 in 2001-2002, in constant dollars. Expenditures vary by state, with the District of Columbia spending the most at $12,046 and Utah the least at $4,674 per student.
Total federal, state, and local spending for education, both public and private, climbed to $745 billion for the 2001-2002 school year. Sixty-one percent, or $454 billion, was spent on K-12 education.  Local funding accounts for approximately 44 percent of pending, state 49 percent, and federal 7 percent. 
The average private school tuition, according to a 2003 Cato Institute study, is $4,689. The average private elementary school tuition is less than $3,500, and the average secondary school tuition is $6,052. 
In 2002, taxpayers spent an estimated $108 billion on education at the federal level, of which about 43 percent went through the Department of Education. The Departments of Health and Human Services, Agriculture, Labor, Defense, and Interior also spent large amounts of money. 
Fifty-three billion dollars went to elementary and secondary school programs. Just under half of this amount was spent on programs under the Elementary and Secondary Education Act (No Child Left Behind Act) and on special and vocational education. 
Over half of full-time undergraduates attending four-year colleges and universities receive federal loans or grants. While participation in federal higher education programs was higher among the poor, a quarter of undergraduates from families with incomes over $100,000 received financial aid. Discretionary programs alone cost taxpayers $22.6 billion in 2003.
Tuition and fees at public and private four-year institutions have risen 38 percent in the past ten years. In the past 22 years, the cost of a public four-year college education has increased by 202 percent. The average tuition at a public four-year institution is over $4,000, and the average private college or university tuition is $18,000. 
All public post-secondary two-year institutions, 81 percent of public four-year institutions, and 63 percent of private four-year institutions offer remedial courses in reading, writing, or mathematics.

The average salary for public elementary and secondary school teachers is $44,367. Salaries in the 100 largest cities range from $25,409 to $84,310.

According to the most recent Department of Education statistics, the pupil-teacher ratio at public schools is 15.9 to one. The average class size is 21.1 for public elementary schools and 23.6 for public secondary schools. 
As of 2002, 99 percent of public schools have access to the Internet. The ratio of students to computers with Internet access in public schools is approximately 4.8 to one. 
Despite higher than average per-pupil expenditures, American 8th graders ranked 19th out of 38 countries on the most recent international mathematics comparison, the Third International Mathematics and Science Study-Repeat (TIMSS-R) of 1999. American students scored 18th out of 38 countries in science.  In combined scores of mathematics and science literacy, 12th-graders in the United States ranked 18th out of 21 countries on the 1995 TIMSS assessment.
On the most recent Program for International Student Assessment combined reading literacy scale tests, American 15-year olds scored near the average. Of the 27 countries that participated, Canadian, Finish, and New Zealand students had the highest scores. 
Parental choice measures have passed in almost every state. 
In six states—Colorado, Florida, Maine, Ohio, Vermont, and Wisconsin—and the District of Columbia, students may use publicly funded scholarships to attend a private school of choice.
Six states offer tax credits or deductions for education expenses or contributions to scholarship programs.
Forty-one states and the District of Columbia have enacted charter school laws.
Fifteen states guarantee public school choice within or between districts. (Other states have choice programs that are optional for districts, target only specific populations, and/or require that parents pay tuition.).
Thirty-eight states and the District of Columbia have privately funded scholarship organizations that provide tuition assistance to more than 60,000 students.
In all 50 states, home schooling is legal. As many as 2 million students are home-schooled nationwide.
