The sessions are the disciplinary actions assigned after the third in line to the crown was caught on video referring to a fellow solder as a "Paki," PEOPLE has confirmed.
The news also comes a day after it was reported that Harry, 24, told a comedian, "You don't sound like a black chap."
On Thursday, comic Stephen K. Amos, the target of Harry's "black chap" remark at Prince Charles's 60th birthday party in November, said there were no hard feelings towards Harry and he (Amos) had not taken offense.
"As a comedian it is my job to find the funny. I was honored to be asked to perform at the 60th birthday comedy event for Prince Charles," said Amos. "I do not believe Prince Harry was racist to me."
He added, "I am more than happy to contribute to the debate surrounding race relations, but I will not allow comments taken out of context to obscure the real issues."
Lessons to Start SoonThe army course in diversity will take place soon, royal insiders tell PEOPLE. Harry is expected to attend the lessons over a period of days.
Thursday, Harry's office at St. James's Palace told PEOPLE, "Prince Harry has said he is sorry for his remarks. He has been subjected to the normal army disciplinary procedures."
The Ministry of Defense added in a statement, "The Army has concluded its considerations in relation to this case."
