Our Redeemer Lutheran Church will close its preschool through sixth-grade school after the 2012-13 school year, the church announced Thursday.

However, the church said its Lutheran High School will be expanded to a grades 7 through 12 school, from its current 9-12 program. The change will take effect with the 2013-14 school year.

The church said in a news release that declining enrollment prompted it to close the elementary school.

“Regrettably the decline in enrollment during recent years has made it necessary not to re-open the lower grades for next year,” the church said in a news release.

The church said its elementary students will be encouraged to enroll in one of the other Lutheran schools on Oahu: Our Savior Lutheran School in Aiea, Saint Mark Lutheran School in Kaneohe, Trinity Lutheran School in Wahiawa and Good Shepherd Lutheran Preschool in Kalihi.
