As a result of Sylvan Learning Systems Inc.’s franchise sales growing more than 150 percent last year, the company is franchising off its Washington-area centers to local entrepreneurs and business operators.

The Baltimore-based company, which private tutors pre-K through 12th graders, sold 94 domestic franchise territories last year, compared to 37 in 2007.

“Individual people who know their communities have a better success rate than company-owned operations,” said Curt Hapward, Sylvan Learning’s vice president for franchising, who calls the franchise growth “significant.”

The current demand for supplemental education services is strong and the market is projected to continue with double-digit growth, according to Eduventures Inc.

Sylvan plans to convert more than 40 existing company-owned centers in D.C., Atlanta, Dallas, Las Vegas, Philadelphia, Salt Lake City, Houston and Milwaukee to franchised centers. In those markets, franchisees could generate sales from existing centers ranging from $200,000 to $1 million.
