Hello!

I am looking for information on regional and national competitions for
the K-12 (Kindergarten to 12th Grade/High School) sector in the U.S.A.
and Canada.

More specifically, how many official competitions are held every year;
how many schools/teams participate; what is the lowest grade at which
a recognized competitions exists; Are the competitions categorized on
the basis of grades (for e.g. do 7th and 8th graders have a separate
competition??)

Thanks, in advance.
