O = original unadjusted model; Med, Zero, and Full = all schools have implemented the country-specific median, the least possible, or most possible level of TICS within the country, respectively. A blue confidence interval with a downward arrow indicates a significantly lower rank than the original scenario (e.g. Qatar for zero TICS scenario in biology)
