<p>Your math is wrong, because you’re not considering scale. You math works for a school with 8 students.</p>
<p>Let’s say a school has 800 students and 100 faculty. That’s an 8:1 student:faculty ratio. If they add 8 students but no faculty, their faculty ration is still 8:1 (808:100 still rounds to 8!) They’d have to add fifty students before their student:faculty ratio would change. As schools increase in size, the number of students they can add without changing the official ratio goes up.</p>
<p>That said, I don’t think bigger is better. Just be careful about the ol’ algebra.</p>
