Mensa, the elite high-IQ society, requires an IQ of at least 132—placing members in the top 2% of the population. According to his parents, Dr. Rose and David Harris-Birtill, Joseph first started indicating extraordinary development at birth. Membership in Mensa demands an IQ level of at least 132—putting members in the top 2% of people. Identifying their son's special abilities, Rose and David made the decision to contact Mensa to offer Joseph more resources and a network of support. "We looked online for other help and realized that Mensa had programs for children who were exceptionally gifted," said Rose.
