Introduction 1997, a study of 5,402 homeschool students from 1,657 families was released. It was entitled, "Strengths of Their Own: Home Schoolers Across America." The study demonstrated that homeschoolers, on the average, out-performed their counterparts in the public schools by 30 to 37 percentile points in all subjects. A significant finding when analyzing the data for 8th graders was the evidence that homeschoolers who are homeschooled two or more years score substantially higher than students who have been homeschooled one year or less. The new homeschoolers were scoring on the average in the 59th percentile compared to students homeschooled the last two or more years who scored between 86th and 92nd percentile.
Purpose of the Study The purpose of the study was to analyze the cognitive development of homeschoolers in comparison to those who go through the traditional public school setting. Focuses in this study are test scores and other forms of assessment for mastery.
Methods
• Participant – students ranged from the elementary- secondary rage
• Procedures: longitudinal study where the original research used the same schools and children
• Measures – standardized test
Results
The study found that the average scores of the homeschool students were at or above the 80th percentile in all categories. The homeschoolers' national percentile mean was 84th for reading, 80th for language, 81st for math, 84th for science and 83rd for social studies.
The research revealed that there was no positive correlation between state regulation of homeschools and the home-schooled students' performance. The study compared homeschoolers in three groups of states representing various levels of regulation. Group 1 represented the most restrictive states such as Michigan; Group 2 represented slightly less restrictive states including North Dakota; and Group 3
