From the school district’s page justifying the new course sequence:

“Historically, rigor meant doing higher grade-level material at earlier grades, and equity meant providing all students equal access. The CCSS-M require a shift to seeing rigor as depth of understanding and the ability to communicate this understanding, and to seeing equity as providing all students equal success.”

If the goal is equal success for everyone, you have to hold back the high-achievers so the rest of the group can keep up.

The problem is hinted at here: "equity meant providing all students equal access"

What they are saying is that they refused to keep unqualified students out of the advanced classes. Keeping those students out would have exposed the schools to all sorts of accusations of discrimination, so they didn't do it. Parents insist that low-performing students be in the advanced classes, and the school doesn't say "no", so the class becomes a mess of failure.
