Dr Julian Salisbury, head of sociology at South Cheshire College in Crewe, was given a reprimand this week by the professional practice committee of the Institute for Learning (IfL) for his two violent convictions.
The watchdog was given statutory powers last year and the hearing this week was the first of its kind.
Dr Salisbury, who pleaded guilty to punching a doorman at the Royal Hotel in Crewe after threatening staff with a 4ft piece of wood, was accused of breaching the institute's code of professional practice by committing a criminal offence.
He was fined pound;600 at Chester Crown Court in August 2008 for the assault earlier in January. At the time, Judge Roger Dutton said: "You were involved in a disgraceful exhibition of drunken, violent behaviour and posturing."
Bradley Albuery, representing the IfL, said: "These were two acts of violence committed in a public place where, at one stage at least, Dr Salisbury had a weapon."
Colin Gledhill, representing the lecturer, said: "This is not characteristic, much less typical or predictable behaviour. Dr Salisbury has taken his judicial punishment and has amended his life."
Sarah Baalham, chair of the panel, said: "There is evidence that rehabilitative steps have been taken and there has been strong support and testimony for his professional practice."
But the disciplinary panel decided the offences were relevant to Dr Salisbury's ability to teach and issued a reprimand, which will remain on his record for two years. He was given 21 days to appeal.
