Fort Wayne Carroll and Westfield hold the top two spots unchanged as the first full week of the rankings cycle closes. Yorktown remains at No. 3 and Hamilton Southeastern holds at No. 4 — stability at the top that reflects programs doing what they were expected to do early in the season.
The most notable movement belongs to Bloomington South, jumping three spots from No. 8 to No. 5 on the strength of a strong opening stretch. Center Grove makes a similar climb, moving from No. 9 to No. 7. Both programs are rewarding early-season results with upward movement.
Chesterton and Harrison (West Lafayette) are the week’s new entries — both unranked previously and both earning their first appearance in the Indiana Preps top 15. Their debuts signal that programs outside the traditional power corridors are making early cases worth tracking.
Roncalli drops from No. 11 to No. 15 after a difficult week. Southwood holds at No. 10. Carmel moves from No. 13 to No. 12 and Providence from No. 14 to No. 13, both reflecting modest upward movement as the field continues to define itself.
The full rankings are updated weekly throughout the season.
