A former teacher at a Christian school in Lansdale has pleaded guilty to a charge stemming from a romantic relationship she had with a 15-year-old student.

Nicole Jacques, 26, of Hatfield, entered the plea to one felony count of corruption of a minor in Montgomery County Court on Tuesday. An additional 30 counts, including multiple counts of statutory sexual assault and unlawful contact with a minor, were dropped.

Jacques is a former teacher at Calvary Baptist School, a small private school.

Police learned of Jacques' relationship when the student's father approached Hatfield police with his phone bill. The father had noticed unusual numbers of texts and calls from two phones that police eventually learned belonged to Jacques. Jacques and the student allegedly had exchanged more than 1,000 texts over the course of a year.

The student eventually told police that he and Jacques were involved in what he characterized as a sexual and romantic relationship for about a year, between February 2011 and February 2012.

School officials said that Jacques no longer works at the school and that no illegal activity had occurred while she was employed there.

Police filed charges against Jacques in March. A judge ordered her to undergo "sexually violent predator" and "house arrest sustainability" assessments.
