I have learned that there are two types of attrition. I honestly did not know that academic boredom was a unnecessary attrition or even a attrition at all. I also found the "creating a carnival atmosphere does not improve student commitment to the school" to be a key item to remember. The environment is one thing but to have staff be part of that environment and be in sync really allows the students to see what the school is all about. 

I Also really liked the part about what improved retention looks like  for the entirety of the school.
