Irrespective of whether for all countries the schools have the least possible (Zero), the most possible (Full), or each country's median (Med) level of TIMSS topics implementation, the ranks are quite stable.
Based on their resources and interest, schools may choose to adopt a high-intensity model incorporating many levels targeting students of varying motivation, or a lower-intensity model providing a baseline level of GH topics to all medical students, or a combination of both.
In order to analyze proportions at the level of each topic oversampling at this level was allowed to obtain at least 40 citations per topic.
