The 21-year old striker was called up to Roy Hodgson's Three Lions squad for last weekend's Euro2016 qualifier with Slovenia and Tuesday's friendly with Scotland.
Berahino was not used by Hodgson in either match, and appeared to be sulking late in the Scotland match, but Baggies boss Irvine believes it would have been a great opportunity for the England U21 ace to learn from his country's best.
"There's certainly no benefit to sulking," he said.
"He has to look at the last two weeks as a great experience - one that helps him to become a better player. If that helps him to raise his game to another level, then fantastic.
"We will get the benefit of that and ultimately Saido will as well.
"It is vitally important he has learnt a lot in these last two weeks and that helps him make the progress he needs to continue to make.
"He knows he has a lot to do to continue to develop to become a regular at that level. I really hope this will give his season yet another boost."
So far this term, Berahino has scored seven Premier League goals in 11 appearances for Albion who currently sit 13th on the table.
