Jordan Clarke, Callum Wilson and Shaun Jeffers have all committed their futures to Coventry by penning new contracts.
Defender Clarke has been a regular fixture in the Sky Blues first team over the past two seasons and has signed a three-year deal.
England Under-19 international Jeffers and fellow striker Wilson have agreed two-year extensions.
"These three lads have all progressed through our academy and it is encouraging to see that we are producing the sort of talent that can feed the first-team squad," said manager Andy Thorn on the club's official website.
"In the days of so many loan players, there is no question that supporters prefer to see players progressing though the ranks.
"It is vital for a club like ours to produce homegrown talent which can supplement players we bring in, and equally important that young players are seen to be given a real crack at the first team, because that will encourage others to join."
