Reasons for Concern in YRS Test Scores

Some of the strongest  evidence that a year-round school calendar and its hybrids (balanced calendar, modified calendar, early school start) are futile approaches to  improving school performance can be found in  test scores of year-round schools. 

The focus of this page is on actual test scores, recent and past, from YR school districts.  Other information on  the impact of testing follows the YRS test score charts. More  information on YRS test scores and achievement also can be found on pages elsewhere on this website (See: What's New, Year-Round School, Early School Start, Important Studies).

Ample reason to doubt the value of school calendar change as a means to improve test scores is found in the three years of Stanford 9 test scores from Alexander City, Ala.,  the very first school district listed in the annual directory of year-round schools produced by the National Association For Year-Round Education.  Alexander City schools saw steady declines since switching school calendars, and  had the lowest test scores among the six Alabama school districts that have used year-round calendar district wide for at least three years. (Chart with test scores or all six districts follows.) 

More worrisome data is found in a comparison of these six school districts to traditional calendar school districts in Alabama similar in size and demographics (numbers of children receiving free and reduced lunch).  Three testing and evaluation experts with Ph.Ds who reviewed the numbers compiled by  SummerMatters.com  said the gap in the test scores  warrants an investigation to see if year-round school may, in fact, have a detrimental impact on learning. 

Pressure placed on school districts in recent years by business leaders and their political representatives to raise test scores and  meet  new school accountability standards  find school districts desperate for ways to enhance achievement outcomes. This climate has been ripe for picking by the marketers of school calendar reform. Pitchmen for school calendar change sway school districts with reports of  test score gains from schools with a reconfigured school year -- reports that credible academic researchers largely discredit because of the flawed methodology and comparison data. (See the Research Review, Important Studies Page). Reports cited by year-round school promoters are notable for the failure of their authors to submit the research for peer review, according to Dr. Gene Glass, researcher at Arizona State University.

We hope the body of evidence on test scores posted on this page will give school districts pause when  considering school calendar reform and will  inspire  university-based researchers to examine test scores of year-round districts that are now posted by many state departments of education on the Internet.  After a decade of research and looking at year-round school testing data, our conclusion is this in a nutshell:

When it comes to school achievement . . .
 the Traditional School Year is STILL the
 Best Educational Bang for the Buck!

Evidence of YR School Failure in Six Alabama Districts

Test scores of six Alabama school districts that converted their entire district to a year-round calendar four or more years ago (as of 2001) found no test scoring advantage for third-graders compared to traditional calendar school districts with like populations of free and reduced lunch students. In fact, many of these year-round school districts saw big test score declines since dropping a traditional calendar. Examples of the declines are shown in the chart below of  third-grade reading, math and SAT totals over a three-year period.  Similar declines occurred at other grade levels.

The scores appear to  refute claims by year-round school promoters that school calendar change has academic benefits for at-risk children. Many school districts pay for the extra costs of using a year-round calendar, including fees for year-round school consultants,  from federal funds designated to help children identified as at-risk. The Alabama  test scores indicate school districts are wasting taxpayer money by using  funds designated for  at-risk kids to pay for school calendar reconfigurations.

SummerMatters.com is gathering additional information to help determine the degree to which the wide gaps  in test scores between these year-round and comparable traditional school calendar districts are significantly different by psychometric standards. Three experts on testing and evaluation  who looked at test scores of ALL six Alabama districts, grades 3 to 11, and  across all subject areas,  tell us the scores warrant an investigation to determine if the year-round calendar is a factor in the lower test scores. 

Third-grade scores in reading and mathematics and the SAT average are posted below. Scores for other grades will be posted in subsequent weeks as time permits. The data for all three  years was compiled from scores posted by the Alabama State Department of Education at http://www.alsde.edu.

Scores showing the declines for all grades (3-11) for the Alexander City Schools are posted on the "What's New" page. A compilation of scores for all grades (3-11) for the other  districts will be posted in coming weeks as time permits.

LOS ANGELES - A Los Angeles County Civil Grand Jury recommended the nation's largest year-round school district do a study to determine if the year-round calendar is the culprit in the dramatic test score differences it observed  between the district's year-round schools and traditional calendar schools.

SummerMatters  obtained a copy of the grand jury report issued  in late July 2001. The grand jury reported  that many principals in low-scoring  Los Angeles schools blamed the year-round school schedule  for low scores, saying  year-round school students  "lost 17 days of instruction per school year under this system."

Two lawsuits filed recently in California over education inequities charge the year-round calendar is "academically damaging." 

The table below lists the Stat 9 test scores of the 28 elementary, 3 middle and 3 high schools examined by the Los Angeles Grand Jury. Scores of traditional calendar schools are followed by the year-round schools.

NAEP Reading Test

States with largest year-round school enrollments
perform the worst on national assessment test

            Dominating the list of poorest performers in reading proficiency  in the most recent scores (1998) on the National Assessment of Education Progress test for 4th graders  are those states that happen to have the nation’s  largest numbers of year-round school calendar students.

            Three of the bottom five states--those  with the worst reading performances  ---are also three of the five states with the nation’s largest number of year-round students. In fact, five of the seven states at the bottom of the performance list  published Jan. 11, 2001 in Education Week are states that have had large numbers of students going to school on a year-round calendar for a decade or more.

            California, which has housed the greatest majority of the nation’s year-round students for nearly three decades, is fourth from the bottom five 39 states on the list, which shows the percentage of 4th graders who performed at or above the proficient level on the 1998 NAEP reading exam. In the 2000-01 school year, California housed 1.34 million or 62 percent of all the nation’s public school students who go to school on a  year-round calendar. The Education Week chart  below shows California fifth from the bottom in 8th grade reading on 1998 NAEP tests.

            Hawaii, which in recent years placed nearly 98,000 students on a year-round calendar, is at the very bottom of the 39 states. Nevada, with a year-round enrollment exceeding 89,000, is No. 5 from the bottom.

            Seventh from the bottom is Arizona, which has the nation’s second largest number of year-round schools and the nation’s third largest enrollment (92,072) of public school students attending school year-round. New Mexico, which at one time had more than 10,000 children going to school year-round, holds sixth place from the bottom on NAEP scoring.

            Texas, which is about in the middle on the 4th grade reading list and has the nation’s third largest number of  year-round schools (155), has seen hundreds of schools drop the year-round calendar in recent years.  (see the Reject List.)

            Critics of the year-round calendar charge the stop-and-start year-round schedule does not improve school performance or test scores.

            The following chart  scores for  4th Grade NAEP Reading proficiency lists the top five and bottom five states, as well as the then number of year-round schools and  year-round student enrollment numbers.

More evidence of the detrimental impact of school calendar change on high school students can be found at: http://www.geocities.com/floydcountysos/ . Test scores have DROPPED in almost every grade since Trion City Schools moved their students to a Modified Calendar in 1999.

Average high school SAT test scores in Trion City School District in Georgia dropped 78 points in two years after switching to a year-round calendar. Check out the Floyd County Save Our Summers/Save Our Schools website.

 Testing & Evaluation Update 
Links to recent reports, research, data

Testing has a place in education, but school policymakers and political leaders have lost all perspective on the value of evaluation in their efforts to improve education performance.  For a balanced view on the role of testing in education, we  recommend reading the following reports and research.

Check out these websites:

bulletAn examination of testing and evaluation myths 


For a solid perspective about the value of tests and testing, read the many reports by education research columnist Gerald Bracey. Dr. Bracey, author of numerous books, has a website dedicated to dispelling  myths about  testing and evaluation, and related issues,  and also provides important perspective on so-called summer learning loss in a column that appeared in The Washington Post. His recent book: The War Against America's Public Schools: Privatizing Schools, Commercializing Education, is a  must read for school districts looking at school calendar change as a means to raise test scores.

bulletNo Evidence of Achievement Value in YRS

This report found "year-round schooling's connection to increasing student achievement is debatable. . . . The research to date, as a whole, is inconclusive regarding the degree to which year-round schools affect student achievement."

Rocky Mountain News, May 21, 2002 report by Holly Yettick
--A Denver study finds reading scores are higher for poor children when they attend school with wealthier classmates. The study is important to keep in mind when proponents of year-round schools tout the achievement gains of at-risk kids who are bused to magnet schools in wealthy suburban schools that have been placed on a year-round calendar.
