Location: withheld since this is now a private residence.
Ackley School is now a private residence. It is a nice-looking red-brick schoolhouse with 3 large windows on each side and a large centered arched front door. Above the front door is the schoolhouse identification sign and above that an enclosed bell tower. The windows have arches above them made from bricks that radiate upward from a spot near the center of the window. Rather than the top surface of those arches being curved (like an arch), the outer-more bricks are longer, making the top of the arch be a flat line. I have only encountered this type of trapezoid-shaped arch in one other Michigan schoolhouse, Clover School. The brickwork under the roof all the way around features several projecting rows of bricks, with a row of diagonally-laid bricks under it, making a type of dental molding.
A couple of old school photographs are below:
