TIMSS study: annual teaching hours

Since 1995, TIMSS has measured students' performance in mathematics and science by grade level and used the common curricula of the participating countries to evaluate them. This dataset presents the number of teaching hours per year by discipline. This dataset is no longer updated. Information on the Timss evaluation can be found on the following pages: <https://www.education.gouv.fr/timss-evaluer-les-competences-des-eleves-de-cm1-et-de-4e-en-mathematiques-et-en-sciences-308600> <https://timssandpirls.bc.edu/timss-landing.html>
