There are 16 Missouri-Synod Lutheran churches in the Indianapolis area that support LuHi, 6 of them with elementary schools. Four of the elementary schools on the south side (Calvary, St. John, Trinity, Zion) are the primary feeder schools. Our Shepherd on the west side and Holy Cross-Geist in the northeast are a bit of a hike, but do provide a few students.
Missouri-Synod Lutherans don't have a CYO equivalent program by congregation/parish. Like the Lutheran schools in Ft. Wayne, there is a single football feeder program for kids from from the elementary schools. Unlike the Holy Cross program in Ft. Wayne, the Indy Lutheran Jr. Saints are open to any interested elementary school players from 1st-8th grade. The majority of the kids who enter the LuHi football team from non-Lutheran schools come through the Jr. Saints. However, after 14 seasons the retention of 7th/8th graders as freshmen still averages below 50%. There have been several contributors on nearby public school rosters who came through the program.
