Just saw that US News has preview the top 10 schools for its 2019 ranking. This list is unordered:

Columbia
Dartmouth Tuck
Harvard
MIT Sloan
Northwestern Kellogg
Stanford
UC Berkeley - Haas
Chicago - Booth
Michigan - Ross
Wharton

What this means is Yale SOM has left the top 10 and Ross has entered it. Ross has been showing some good placement stats ($146k average for 2017 MBA grads), with many going into consulting and tech (Amazon likes Ross grads...)

zzzz... boring...

I guess Yale leaving the top 10 is notable. Of course, Yale is still ranked higher than Ross in the FT.

Here's the ordered top 10 list:

Tied for 1. Harvard
Tied for 1. Booth
3. Wharton
4. Stanford
5. MIT - Sloan
6. Northwestern - Kellogg
Tied for 7. Haas
Tied for 7. Michigan - Ross
9. Columbia
10. Dartmouth - Tuck

It looks like they have updated their methodology to discount GMAT scores if a school didn't submit the scores for at least 50 percent of a class:

This year for the first time, MBA programs that reported that less than 50 percent of their full-time fall 2017 entering students submitted average GMAT scores and average GRE quantitative and verbal scores received less credit for those test scores in the rankings.

Specifically, their weighted percentile distributions were adjusted downward by the proportion of the percentage of the student body that submitted test scores in relation to the 50 percent threshold. For example, if 25 percent of the entering class submitted test scores, then the test scores were reduced in value in the ranking model by 50 percent. For the purposes of determining the proportion of full-time fall 2017 entering students with scores, the percentage submitting GMAT and GRE were totaled.

Texas Christain University (Neeley) has been removed from the US News Ranking:

They overstated their average GMAT. Said it was 678 when it was actually 640.

A bit similar to what happened to Temple in the Online MBA Ranking:

From an article I read, they attributed it to human error - whoever filled in the info put the wrong value in the field. They normally have internal processes for checking these things, but for whatever reason they didn't catch it. Was it something as simple as confusing the mean and median values maybe?

Yes, maybe something like that. If they can make a mistake like that, and since this has happened before with another US News ranking, it sort of undermines the credibility of the publication, at least a little.
