The 20-year-old Burundi-born striker marked his full debut for Albion with a hat-trick against Newport in the Capital One Cup and has since followed up by bagging twice for the England Under-21 side.
His equaliser against Finland on Monday night salvaged a point for Gareth Southgate's side after a goalkeeping blunder from Jack Butland put England in trouble.
Clarke is delighted to see Berahino receiving the plaudits and rewards for the hard work he and the coaches at the club have put in for him.
"It's good that we're talking about one of the products from the club's academy," the Baggies boss told the Express and Star.
"You have to show your young players and your academy graduates that there is a path to the first team.
"If you close that path the boys lose impetus and their desire to get to the first team. It's always important if you can and when you can to give them a chance.
"Sometimes it's difficult because it's a results-driven industry and you have to make sure you get the balance right between showing that path and making sure you win the matches.
"But it's great for people like Mark Harrison (academy manager) and Jimmy Shan (under-18s coach) in the academy that they and all the other coaches can see that, if the boys are there, we will give them a chance."
