Eligibility Requirements 


NOTE: Regarding Testing during COVID restrictions:

Because the testing schedules for the ACT and SAT/PSAT tests have been disrupted, we are now accepting the Classic Learning Test (CLT).  Therefore, we will now be accepting a CLT test score in Quantitative Reasoning of 24.

Mandatory Requirements for MHS membership are a one time score on one of the following tests:


Mu Eta Sigma's main objective is to offer a math honor society that provides the homeschooled community a comparable alternative to Mu Alpha Theta, the most prominent national math honor society available to public and private high school students. Mu Alpha Theta membership is based solely on teacher recommendations while our membership is based on standardized test scores. The SAT minimum score we have chosen is the mean score representative of “A level” (93-96 grade average)** students who have recently taken the SAT. The PSAT and ACT scores are simply the scores which correlate to the SAT “A level” score. The IOWA and Stanford* scores are the commonly accepted thresholds to determine honor society distinction. Rather than establishing membership through teacher recommendation which cannot be defined, and has no grade point requirement or test score prerequisite, Mu Eta Sigma defines membership requirements through specific minimum scores. Mu Eta Sigma believes that this offers a more objective picture of the math honor student.


  • A test score of 600 or greater on the  PSAT Math portion

  • A test score of 600 or greater on the SAT Math portion

  • A test score of 26 or greater on the   ACT Math portion 

  • A test score of 26 or greater on the PreACT Math portion

  • A test score of 90% or greater on the Math battery  of the IOWA or Stanford* nationally-normed Standardized Achievement Tests

  • A test score of  24 or greater for the CLT Quantitative Reasoning section


Parent administered tests are not acceptable. Test scores should not be more than 1 year old. These standards are not negotiable.

The Stanford online test is not acceptable as Mu Eta Sigma is unable to ensure that this test has been administered independent from parental input.

Mu Eta Sigma is limited to Homeschooled students


Age - Qualified students shall be those who have entered grades 9th – 12th. 


Home-Educated - Qualified students must be homeschooled students whose education is managed by their parents or legal guardians. A qualified student’s education may include the use of tutors, video courses, Internet courses, college correspondence courses, classes in cooperation with other homeschooled students, and other creative methods that supplement home education.   


Public & Privately Funded Education - Students who are primarily enrolled in a public or private school system (thus eligible for Mu Alpha Theta membership) are not eligible for membership in Mu Eta Sigma, the Homeschool Math Honor Society. A student is “primarily enrolled” in a private or public school for MES purposes if more than 50% of that student's education is provided by the school.  MES defines the public school system to include public schools, tax-funded charter schools, tax-funded independent study programs, or any other form of education that is subject to legal restrictions solely because it is funded by government money or property.
