After 46 years of teaching at Catholic schools, Sister Micha DeHart is retiring from St. John Primary in Prairieville.

DeHart was the last nun working in the St. John Primary and St. Theresa Middle school system, according to a news release from the school.

Before the 2013-2014 school year ended, students, faculty and staff members at St. John Primary and St. Theresa Middle presented DeHart with mementos and gifts for her service to the schools.

Following in the footsteps of some of her friends, DeHart entered the Sisters of the Most Holy Sacrament convent at age 18.

DeHart took education classes at the University of Southwestern Louisiana (now University of Louisiana at Lafayette) for a year, and began teaching the following year at St. Pierre Catholic School in Carencro.

She received a temporary teaching degree and continued to take summer classes toward completing her education degree. Her first class consisted of 42 third-grade students, the news release said.

DeHart taught in Pineville; Pascagoula, Mississippi; Crowley; and one year at St. Theresa of Avila School before returning permanently to St. Theresa of Avila School in 1978 as a Title 1/Chapter 1 reading lab teacher. After seven years, she became a first-grade teacher.

During her tenure at St. Theresa of Avila School and St. John Primary, which is part of the East Ascension/East Iberville Catholic School Partnership, she received the Teacher of the Year Award and the Brotherhood/Sisterhood Award, culminating with the Diocesan Teacher of the Year Award, which she received during the 2013-2014 school year.
