In what order did a boy of a noble family usually pass through the stages of training for knighthood?

Explication

Training began in a lord's household at a young age and moved on to close attendance upon a working knight before the young man was admitted to knightly rank himself, so duties grew heavier as age and skill increased. The craft sequence fails because those three ranks belonged to the workshops of the town trades and had nothing to do with military service owed to a lord.
