A Dallas-based test-preparation company and the College Board have agreed not to comment on the lawsuits they have filed against each other. According to a legal document signed by lawyers for both sides today, “… all parties to this lawsuit are prohibited from communicating with nonparties to the lawsuit, including but not limited to members of the news media….”

Before the agreement, representatives of both the College Board and the test-preparation company, Karen Dillard’s College Prep LP, had talked extensively about their lawsuits.

In litigation filed last week in the U.S. District Court in Dallas, the College Board alleged that Karen Dillard’s company had illegally obtained copies of SAT and PSAT tests before they were available to the public. The College Board also said the company had violated copyright laws by using questions from former SAT tests in its test-preparation materials.

Karen Dillard’s company then filed a countersuit on Monday, asserting that the College Board had improperly obtained proprietary information about the company from one of its former employees. The test-prep company is seeking a temporary restraining order against the College Board to protect the privacy of its clients. —Elizabeth F. Farrell
