A suggestion box left his family stunned after scoring the highest Mensa IQ test score of 162 – at the age of just 10.
Wellingborough Prep School principal Dexter Petican’s perfect result makes him one of the youngest high IQ members of society with the maximum score.
The 6th grader, who lives in Earls Barton, only took a test after a conversation with his grandfather about Sudoku and the crossword puzzle left him wondering what his IQ was.
But he scored 162 on the Cattell III B test, which examines verbal reasoning, giving him a higher IQ than Professor Stephen Hawking, who is said to have an IQ of 160.
Dexter’s mom Chantal, 40, said: âI almost fell off my chair, I was so surprised.
âTaking the test was never having a genius child, it was having fun.
“We are incredibly proud of him.”
Dexter first became interested in taking a test after his grandfather told him about IQ and how to calculate it, leaving the curious youngster wanting to know more about his.
Chantal, a personal assistant at Barclays, looked online but found that Dexter couldn’t take a Mensa test because he was not ten and a half, the minimum age to take one.
After waiting until he reached the minimum age, he traveled to Birmingham to take the test, answering 150 questions in 90 minutes in no time.
And last week, Dexter, who enjoys doing puzzles and puzzles in his spare time, found out that he had not only been offered the Mensa membership, but had achieved perfection.
Chantal said: “He’s a fairly modest kid but he’s pretty happy and proud of himself.
“He’s starting high school in September so that’s a big boost for him.”
Dexter, an avid sportsman who plays cricket at Overstone Cricket Club and rugby at Old Northamptonians, enjoys everything maths.
And Chantal said he wants to be a mathematician or a scientist when he’s older.
She added: “He’s so young – the world is his oyster.”
A UK spokesperson for Mensa said: âWe are delighted to welcome Dexter to Mensa, where he joins a growing community of children and adolescents.
âIn addition to the chance to meet other Brilliant Sparks, Dexter can join Mensa events and special interest groups to help him develop his interests and discover new ones.
“Her parents can also join our Mensa Family Groups to tap into the support network of other parents who understand the pleasures and challenges of raising a Bright Spark.”
Mensa was founded on October 1, 1946 in Oxford. This is the idea of ââtwo lawyers, Lancelot Ware and Roland Berrill, who discovered a mutual interest in high intelligence and its applications during a chance meeting.
Their founding principle – that all members are equal regardless of age, sex, nationality, religion, race or politics – is still at the heart of society today.
There is only one criterion for membership: an IQ measured in the richest two percent of the population.
Once entered, all members are equal and individual IQ scores are rarely mentioned. Mensa is a round table organization – the word Mensa actually means table in Latin, although many people still think it must be an acronym.
There are around 140,000 Mensa members worldwide and around 19,000 in the UK and Ireland, ranging in age from three to 102 years old.
Notable people who have reportedly qualified to become members of Mensa include TV presenter Carol Vorderman, Olympic swimming champion Adrian Moorhouse and Roger Squires, Guinness World Record crossword compiler.
