Interestingly, 46.66% of first round offers went to Tier 4 students is very consistent with the current system. 30% + 17.8% is the max cap for Tier 4. This only means that the majority of the 30% rank students are in Tier 4 for Skinner.
The minimum scoring requirements have nothing to do with Tier system. Even removing the 30% rank seats won’t change that.
If you insist that 25% of the kids must come from Tier 1 or Tier 2, then you must abolish the minimum scoring threshold for the elementary schools. With the current CPS CEO, this might actually happen. But then again, it has nothing to do with the 30% rank seat.
For academic centers and SEHS, the new quota of 25% for each Tier will simply force these top schools to separate students into regular vs AP classes. This will reduce the class offering for SEHS with smaller student bodies. I predict the national ranking of Payton and Northside will drop like a rock. Maybe then everyone will be happy.
