What drives Collinsville’s History grade
On its age, its old homes and the National Register, Collinsville is more historic than 28% of U.S. towns. Its share of homes from before 1940 holds the grade up; its National Register listings pull it down.
C
HistoryA character grade: shown, never part of Collinsville’s overall grade.
Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so Collinsville’s 0.0 sits below most of its state (34% of Texas towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be C. The pre-1940 share is a Census survey estimate (±5.1 points). The founding year is the first post office, not a stated founding date.

What stands out about Collinsville’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1904, Collinsville Academy was built. The school had two stories and six rooms, and could accommodate about 400 students. The school was rebuilt in 1941 with the intention being to help the citizens of Collinsville retain jobs during the Depression, according to the older citizens of the community. A 20-room school was built to replace it, and continues to be used as an elementary school. A high school and junior high were built in 1995.
The Collinsville post office opened in 1872, the earliest record of the town by name (U.S. post office records).
