A growing number of employers are recognizing the benefits of supporting their workers' educational and professional development, a new study shows.

According to Accountemps, a Menlo Park, Calif.-based staffing firm, nearly 95 percent of 150 senior executives surveyed said their companies reimburse workers for college and university tuition, as well as other forms of professional training.

Only five percent said they don't cover university tuition, while two percent said they don't pay for outside professional training, the survey found.

"Providing educational and professional development opportunities helps companies attract top performers, maximize productivity and boost retention efforts," Max Messmer, chairman of Accountemps, said in a statement.

Among other benefits for employers, Messmer said employees who continue to pursue an education throughout their professional careers remain intellectually challenged and are more capable of taking on larger work responsibilities.
