The article still pertains. I worked in admissions as a student assistant many many years ago at a school that was technically need blind in admissions. Admissions gave the very top accepts merit money(very few) and if they had financial need, the Financial Aid office, a completely different place not even in the same building, would make sure that student had full need met. If there was any need left after the scholarships, those kids got every bit of it covered by grants.
Those who were still top picks but not getting merit money, were coded as such and they too tended to get full need met with grants.
The next group of kids got self help and grants, but still got full need met. No gaps yet.
The last group got whatever state and government aid existed, and was gapped.
So the school was need blind in admissions but did not guarantee to meet full need. However, something like 90% of the kids did get need fully met
I’ve known Adcomms at schools that are not need blind in admissions in that they would rather accept a dozen low need kids (but still qualifying for need) for the amount of money it would take to fully meet the need of a high need kid. Those schools may also meet 90% of need, maybe 100% of it, but the methodology is completely different.
