Johnnie Jackson (Swindon and Colchester), Stephen Kelly (Southend and QPR), Lee Barnard (Exeter), Dean Marney (Swindon), Ronnie Henry (Southend), Shwan Jalal (Woking) and Robert Burch (Woking) have all now tasted first team football and Colin feels that they have all benefited from playing against players from outside their own age-group.
"Stephen was out and they got to the play-off final," said Colin. "He was at Southend before and did well there. QPR fancied him and it was another division up and we hoped that it would be competitive and they would get in the play-offs and that is what's happened.
"They were pleased with him, we are pleased with what we've seen of him in league football and it is the next part.
"Dean Marney has been out and done alright at Swindon, Jacko, Ronnie Henry and the two goalkeepers have been out.
"It is a good education and you need a bit of that playing against men. It is definitely more competitive than some reserve games tend to be."
Colin added that he does notice a difference in the outlook of the boys when they return to the club.
"A little bit. You can see that they are very appreciative of the facilities we've got here and the way they are treated.
"It is completely different at those clubs - they don't have the finance or structure that we've got in place here.
"It brings them back down to earth going out to these places and they've got to mature. They've got to drive, stay in a hotel or digs and they've got to make their own way out of their normal routine.
"While they have got to do well on the playing field, a lot of it is what they do off the field with their time while they are away from home."
Colin Calderwood is pleased with the result of the loan spells undertaken by a number of our young players last season.
