For people of all ages, achieving a high score on an IQ test can lead to membership in Mensa International, a society that welcomes people from around the world whose intelligence is considered to be in the top 2 percent of the population, according to the organization's website.

James and LeAnne LeSage, a pair of siblings from Naples, Florida are the latest individuals to be granted membership into Mensa, Naples Daily News reported. However, what sets these two apart from others is the fact that they are 6- and 3-years-old, respectively, making them some of the youngest members of the society.

After James took an approved intelligence test and LeAnne completed an assessment that is designed for preschool children, both siblings were accepted into Mensa, the news source stated. Although their parents did not reveal the pair's exact scores, they said that they both placed in the top 2 percent of their specific tests.

Parents who feel that their children possess above-average intelleligence may want to see how they perform on a kids IQ test.
