How Important Is School Size?

Which is better? Big or small? It all depends on what's a good fit for your child.

What's the Right Size?

When it comes to school size, there is no right size that works for every student. Some students thrive in a smaller environment where they get lots of attention, while others prefer the variety of activities and peer groups available in a larger school. Certainly, small and large schools each have their pros and cons.

Small Schools, A Growing Trend

In the 1960s the general thinking was that larger schools offered more comprehensive instructional programs of greater quality at lower costs than small schools (generally defined as schools of less than 400 to 500 students at the high school level) did. But in recent years researchers have discovered that the cost savings provided by large schools have had a negative effect on student achievement and graduation rates. As schools get bigger, student achievement declines and larger schools have higher rates of absenteeism, dropouts and discipline problems. In addition, "Dollars and Sense II," a 2005 study of 25 different small schools across the nation found that, on average, small schools spent 17 percent less per student than comparable schools in their districts while achieving equivalent or better results.

As a result, there has been a growing trend toward creating small schools, and schools within schools, (particularly in high schools) to better engage students and give them more attention. The federal government has issued more than $94 million a year in experimental grants for small learning communities or "SLCs." School districts may use these grants to create smaller schools within schools. Since 1999, the Bill and Melinda Gates Foundation has committed more than $1.8 billion to creating 1,500 small high schools around the country, and the Michael and Susan Dell Foundation has committed an additional $32 million to further their efforts, particularly in urban areas.

How Have Small Schools Fared?

The Gates Foundation sponsored a study of 24 small schools in 2005 to look at their effects. The study found that some students talked about their teachers as having higher expectations for them because teachers knew more about the students' capabilities. The 2005 Gates report found that students in small learning communities increased their English test scores but showed a slight decline in math.

In the Newsweek 2007 list of top high schools in the U.S., 22 of the top 100 schools had fewer than 100 students in their graduating class; the number of small high schools on that list (which is based on the number of students taking college-level tests: Cambridge, International Baccalaureate and Advanced Placement) has dramatically increased over the past 10 years.

However, overall research on the effect of school size on student achievement has been limited. Most recently, another Gates Foundation study looked at the first graduates of 14 of New York City's new small high schools in 2006. The study shows that attendance was high, ninth-grade promotion rates were high and a majority of the students graduated. A significant number of those graduates were accepted by colleges and more than half of them were the first in their family to attend college.

But other Gates-funded small schools have run into trouble. In Denver, Colorado, the district used $1 million of Gates Foundation money to convert the 1,100-student Manual High School into small schools. In the process, electives, advanced placement and foreign language courses as well as popular activities like choir, debate and athletic teams were cut back. Many unhappy students left causing enrollment to plunge as well as graduation rates. Denver eventually closed the small schools. The Gates Foundation has realized that curriculum and instruction may be as important as school size.

Comments from readers

"My school has around 4,000 students. There are few fights and few problems. Everyone has their own group of friends and doesnt mess with anyone else. I love my school and how bi i is. Academically we are the best school in the state. Lexington high school. Lexington SC look it up "
"My son attends a small school. His school and teachers only worried about how well the kids do on the state test. Since the state test scores determine how much money the school receives from the State. Larger schools are not as concerned with the test since there are more children taking the test. "
"i am currently being home schooled until next year and kids want a school they can have fun learning in"
"What language is mostly spoken in your school? I hope English is the first language for all the staff and students; and that the conferences, PTA, and all activities are conducted in English. After reading some of the comments I am scared. We are all still live in America, and diversity is beautiful, but we all speak our native tongue ENGLISH first."
"Our high school has roughly 1,700 students. Any discipline problems are met promptly and appropriately. There IS a sense of community, even though the school is large. There are programs within the school to provide for students with a variety of issues. There is also plenty of parental involvement. The school is PACKED during parent-teacher conferences. There is diversity!! There is also tolerance & understanding for students who are gay, transgender, and who have other issues, such as, bi-polar disorder, autism, etc. It is an open-minded and intelligent community in our school. The curricullum is varied and we have a lot of AP classes. Also, study-abroad programs. A student can basially get whatever he or she needs or wants. In a safe & close-knit environment!"
"This school is too big for the population of students. My son is not being schooled the way he should. We went to a PTA meeting and we walked away. It was all in a foreign language and they gave us ear phones for us to listen to it in english. This is unacceptable in an english speaking country. This really sucks, and is definitely unaccepable. What the fxxk is this country coming too. I thought we lived in AMERICA. I can't even teach my son english much less take part in his education or PTA without putting up with something that isn't english in kindergarten.DISD really sucks. Please respond, and tell me why I must go to an AMERICAN english speaking school and put up with this BS.You can take PTA and stick it."
"' School size for High Schools is different than middle or elementary. Optimum size for HS is around 600 students. Middle school is 4-500 and elementary buildings should never go over 400 if that. Students need contact with caring adults. When the school is smaller, the adults know the brothers and sisters as well as have a better chance of knowing the parents. Special services need to be available and can be provided district wide rather than on a building level.'"

"I don't think that it's the size of a school or class room. It's the quaility of the teachers.How far are they willing to go for a childs education?It starts with the teachers."
"Our district has less than 600 students and spends $3,000 per student more than our neighboring district which has 2,000 students. Should we be talking merger? Although interesting, it appears the research cannot help us answer this question at this point. Could you please keep this 'size' issue active as research continues. Thanks."
"All children learn differently and that will always be a problem. Each teacher should include a variety of teaching methods and if a student does not appear to be learning in that particular class there should be a option of switching that student to another teachers classroom, upon review and discussion. All would benefit. some are just better suited to others and we need to leave some flexability in our structuring of classrooms. Some students will learn no matter what and other just will not progress - will need further help maybe one on one. The schools budgets do not allow room for special needs of students and why should one child get more than others when all pay the same taxes, this will always be a problem and there is no fair or 'right' answer. "
"Our high school has over 3000 students. the problems with overcrowding are too numerous to list. The school prides itself on having numerous AP classes and IB classes. The less talented kids are relegated to dummy downed classes.The ratio of students to counselors is 500 to 1.There are no technical courses in the trades or commerce.The basic premise is that all kids should go to college. How non realistic can you get?"
"No school should have more that 500 students! 100 in each grade, so that teachers know the children and children their teachers"
