According to a friend who volunteers in the Santa Cruz CA Public Schools, the official view is that 1 is a prime, because its only divisors are 1 and itself. However, a teacher did mention that in more advanced mathematics, 1 is not a prime.

Do they also teach that unique factorization is false? Or is it stated as "numbers > 1 have a unique factorization into primes other than 1"? Andy
