The quick answer is no. The so-called Age of Accountability has been commonly thought of as 12 years of age. There is no written indication of this in the Bible. It is the supposed age where children were accountable for their sins, unless they repent of their sins and put their trust in Jesus. This is based on a Semi-Pelagian type of belief. Pelagianism: the teaching that people are not born with fallen natures. They will fall when they choose to sin, and that would be the age of accountability. Semi-Pelagianism: teaches that people are born with fallen natures, but they are capable of choosing between good and evil.
