IQ and Educational Needs

 

Statistical information from Guiding the Gifted Child, 2002.

         The mean, or average, IQ is 100. Standard deviations, in most cases, are 15 points.

         The majority of the population, 68.26%, falls within one standard deviation of the mean (IQ 85-115).

This is the intellectual ability range addressed by the standard school age/grade-based curriculum.

         13.59% of the population is between the first and second standard deviation below the mean (IQ 70-85), and 13.59% is between the first and second standard deviation above the mean (IQ 115-130).

Students on both sides of the curve require a modification to the curriculum from that provided to mainstream students to address their needs.

         2.14% of the population is between the second and third standard deviation below the mean (IQ 55-70), and 2.14% is between the second and third standard deviation above the mean (IQ 130-145).

These exceptional students on both sides of the curve require an individualized curriculum to address their individual needs.

         0.13% of the population is more than three standard deviations below the mean (IQ <55), and 0.13% of the population is more than three standard deviations above the mean (IQ 145-160). Thus, 13 out of 10,000 individuals score above 145 and are considered profoundly gifted.

These students on both sides of the curve are very exceptional and require individualized accommodations to address their needs.

         Approximately, one out of 30,000 individuals (.003%) is more than four standard deviations above the mean (IQ >160). 

These students with an IQ of 160 and above require extremely exceptional educational accommodations to meet their needs.

Policies & Practices

         For students below the average range, educational accommodations are mandated at the federal and state levels. Twenty cents of every education dollar funds special education. See the Individuals with Disabilities Education Improvement Act (IDEA) http://idea.ed.gov/ and the U.S. Department of Education Budget www.ed.gov/about/overview/budget/news.html?exp=0

         For students with intellectual abilities above the average range and into the extreme end of the intellectual continuum, there is no federal mandate for educational accommodations and no federal funds budgeted. States and districts that do provide educational accommodations for gifted students seldom recognize the wide spectrum of abilities within the various standard deviations.
