First, this thread is about a public school district with 3 or more high schools all having success at the same time. Not about a private school and a nearby public school.
Comparing a district with 3 school to a district with 4 or more schools is not an equal comparison. The more schools the lower the probability that all schools will have success at the same time.
Community High School District 155 has had a few periods where 3 of the 4 high schools have had success at or near the same level as the LW 210 schools. Having all 4 schools would be rarer than anything LW210 is experience right now.
U46 schools (Elgin, Larkin, Streamwood, South Elgin, Bartlett) have never had more than 1 or 2 schools succeed at a time. Again, harder for 5 schools to do it at once than three schools.
On the flip side, 2 school districts like Naperville 203 and Wheaton 200 have had longer periods of greater success than LW 210 has, but the probability is better with only 2 schools.
