In a column Chamblee wrote for Golf.com, he gave the world number one an "F" grade for his five-win season and compared cheating in a school test with a number of rules violations committed by Woods.
Woods received penalties for illegal drops at the Abu Dhabi HSBC Golf Championship and the Masters and was penalised two shots for moving his ball at the BMW Championship. Chamblee's column also mentioned a drop at the Players Championship which attracted questions.
In the offending column, Chamblee recalled cheating in a school maths test and how his teacher had crossed out his "100" grade, replacing it with the letter "F". Chamblee ended the column by doing likewise as he graded Woods' season.
He appeared on the Golf Channel on Wednesday to discuss the issue and, while he stands by his assessment that Woods "was a little cavalier with the rules", he acknowledged he should not have compared the infractions to his own indiscretion.
"In offering my assessment of Tiger's year and specifically looking at the incidents in Abu Dhabi, Augusta, Ponte Vedra and Chicago, I said Tiger Woods was cavalier about the rules," Chamblee said. "I should have stopped right there.
"In comparing those incidents to my cheating episode in the fourth grade, I went too far. Cheating involves intent.
"Now, I know what my intent was on that fourth-grade math test. But there's no way that I could know with 100 per cent certainty what Tiger's intent was in any of those situations. That was my mistake."
Chamblee apologised for the column last week on his Twitter page, a move he has now ackowledged was prompted by his son.
"At times I can be a bit forceful with my opinions, and some would say too forceful too many times," he said in Wednesday's interview. "That was obviously the case in this instance - so much so that even my son chimed in on this issue.
"He said, 'Dad, if you'd been more diplomatic in what you wrote, perhaps people would be talking more about the issue than your assessment'. He's a smart kid.
"It wasn't until after he said that that I offered my apology on Twitter. Maybe I should have let my son read (the) column before I hit send on the email."
Chamblee also stressed that the column was not endorsed by his regular employers at the Golf Channel and revealed he would be ending his association with Golf.com at the end of this year.
