What “Mobility” means here

In the rankings engine the soft weight labeled Mobility is easy to over-read. Its hint on the dial is explicit: share of Pell Grant students. Higher Pell share scores higher inside your filtered subset. That is an access composition signal — who the college enrolls with need-based federal aid — not a prediction that any one student will “climb,” and not an Opportunity Insights–style mobility percentile.

A campus can look exclusive on admit rate while enrolling few Pell students. Another can enroll many Pell students and still need scrutiny on completion and earnings. Those are related questions, not the same question. Mixing them into one prestige story erases the difference.

How to use the dial honestly

• Raise Mobility in the weighted explorer when Pell access matters in your shortlist — knowing you are optimizing Pell share, not inventing mobility odds.
• For a single-metric view, open colleges serving the most Pell students or the leaderboard’s Pell axis.
• Pair Pell share with graduation and earnings weights (or lists) when you care what happens after enrollment — those are separate Scorecard measures.

These figures remain institutional aggregates. They do not guarantee what happens to one student. They do help you notice campuses that look selective while doing little Pell access work — and to stop treating “Mobility” as a synonym for destiny.
