It has been just over 300 days since I started this blog, and in that time, I have written 95 posts. I started it as a dinky little Tumblr account, and have grown into a full-on Blog. And while I started by just sharing this with my students and friends, there are now people, whom I have never […]
Core Index
More Evidence that High Schools benefit from the Core Index
Last week, I showed that the Core Index was more generous to High schools than the API had been. Here is another way to look at it. Below is a regression of the data, showing the trend line. The trend line is predictive – it attempts to predict the Core Index score from the API. […]
The Core Index is much more fair to High Schools, tougher on Elementary Schools
A few days ago, I showed that the old measure of schools, the API, was extremely generous to elementary schools. The new Core Index has (sort of) replaced the API. There are several key differences: It uses the new SBAC test instead of the old CST. It uses a lot of comparative scores, to attempt to […]
Is the Core Index correlated to the API score?
One of the critiques of the API score used for over 10 years was that it only focused on test scores to rank schools. In reaction, the new Core Index score is only 60% based on test scores, while 40% is based on other factors like English Learner progress, absenteeism and suspensions. Yet, in previous […]
How did your school REALLY do on the Core Index?
As we look at the Core Index Scores, we are immediately hit by how much demographics of a school affects a school’s success. As I discussed in a previous post, the top schools are whiter, wealthier and have less English Learners than most of LAUSD. So, in an attempt to level the playing field, I […]
A Better Way to Look at Core Scores – The FO’REAL Score
In my last post, I made this argument: it seems unfair to me that schools that are wealthier, whiter and with less English learners seem to do better on the Core Index Score, the new measurement for LAUSD schools. According to my multiple linear regression (MLR), 65% of the variance in index scores can be […]
Are the top scoring School Quality Index schools really role models?
In LAUSD, there are 23 schools that received a score of 95 or more on the School Quality Index score created by the Core Waiver program. A lot of praise has been heaped upon those schools – but I question whether they are really “role models” for the rest of LAUSD. Schools with scores above a […]
Do span schools outperform traditionally leveled schools?
Source: Coredistricts.org Index File (http://coredistricts.org/core-index/download-index-file/) Span schools are alternative style schools to the traditional grade breakup of schools (K-5, 6-8 and 9-12). In the California Core Districts Database (which includes Los Angeles, Fresno, San Francisco, Long Beach and Santa Ana) there are three types of span schools: There are fifteen K-8 schools, eleven K-12 schools […]
