Notice the word or in this sentence... they don't know the law!!! take this in to them...
Exemption is obtained by "submitting to the student's school a statement of exemption signed by one parent or guardian or the emancipated student OR student eighteen years of age or older that the parent, guardian, or student is an adherent to a religious belief whose teachings are opposed to immunizations OR that they have a personal belief that is opposed to immunizations."
OR that they have a personal belief that is opposed to immunizations."
and a little further down...
C.R.S. 25-4-903 (2006)
