I'm taking the act saturday what calculators are permitted

If your in 11th grade, I believe any handheld calculators.

This is from the act site
I googled "act approved calculators list" and clicked on the act.org link

any calculator that can't do algebra is good
so scientific or  four function calculators (the cheap ones) are good
some graphing calculators are banned

it's easier to find te ones that are banned
TI-89 and higher is not allowed
TI-Nspire CAS is banned
calculators that have "computer algebra system functionality" are banned (you can't use a calculator that can solve for x for you)
calculators can't have QUERTY keyboard layout
calculators can't have pen input

can't use Hewlett-Packard Prime, or Hewlett-Packard48Gll or any Hewlett-Packard with model number beginning with HP40G, HP49G, or HP50G

you can't use these casio calculators
fx-CP400 (ClassPad 400)ClassPad 300ClassPad 330Algebra fx 2.0All model numbers that begin with CFX-9970G

make sure you bring extra bateries and know how to use your calculator
make sure it doesn't make noises or distract other people as well
