The tiny principality of Andorra (population 78,000) has a long-established chess in schools program, which started way back in 1987. The current Programa d’Escacs Escolar has an annual budget for the program of about €90,000. FIDE’s development fund will this year contribute about 5,5 % of that spend.
Fascinating that 93% of chess in schools in Andorra now takes place during normal school hours, and only 7% after school.
