Vocal Selection note changes?

Do vocal selections typically change the notes a bunch? I’m pretty new to the scene and my music reading might be off, but everything I’ve read online says Burr’s highest note is an A4, yet the vocal selections says he has quite a few notes above the grand staff in Wait For It? My voice teach also said the Rent vocal selections had One Song Glory higher than it originally was performed, so is this just normal?

I don't know about Hamilton, but yes, the Rent thing is true. One Song Glory is printed in G, whereas the official score has it in G-flat (a half-step lower). And yes, unfortunately that is common; publishers of vocal selections want the average person to be able to play what's inside it, so they often publish songs in easier keys.
