Czech Astronomical Olympiad
The Czech Astronomical Olympiad is organised for pupils of elementary and secondary schools in the Czech Republic. It is very popular among younger pupils because of the opportunity it provides to use all informational resources (with the exception of the help of other persons). Practical observational tasks are required in the correspondence round. After the final round of categories "EF" and "CD", a two-day workshop is held to select candidates for the International Astronomy Olympiad. The Czech Astronomical Olympiad is supported by the Ministry of Education, Youth, and Sports as a science competition in category A.  History.
