Teakwood Capital, the Dallas-based private equity firm, is buying a control investment in ExamSoft, an exam administrator and test creation software provider.

Terms were not disclosed and calls seeking comment were not addressed by press time. Daniel Muzquiz, chief executive of ExamSoft, will remain with the company after the deal completes. Teakwood’s Shawn Kelly, a managing director with the PE firm, worked on the deal.

Kelly said that Examsoft, with a “fully financed growth strategy,” will “continue to grow very rapidly in the years ahead.”

Other Teakwood investments include Zoom Interactive Marketing, the Whitley Printing Co., Global Acceptance Credit Co. and myopenjobs.com, which it bought in September 2009. The private equity firm’s other education investment was in Manexa, which it bought in July 2009, an online platform allowing companies and groups to provide online education to employees and members.

Deals in the education space have increasingly emerged in 2010, often with private equity firms making bids to become control stakeholders.

In March, PLATO Learning, an online solutions provider, was taken private and sold to Thoma Bravo for about $143 million.

In February, a consortium of PE investors including Berkshire Partners, Advent International and Bain Capital Partners agreed to a $1.1 billion take-private of Dublin-based e-learning company SkillSoft. Also in March, PE firm Hudson Ferry bought Contrax Furnishings, a Floridian maker of classroom furniture.

Last year, Sterling Capital Partners acquired assets from a pair of multimedia education companies—but there have been some strategic deals as well. Voyager Learning Co. merged with Veronis Suhler Stevenson’s Cambium Learning Group and the Princeton Review bought Penn Foster Education from its former PE owner The Wicks Group.
