The Regnum Christi schools lead the educational rankings for their innovation and international training. The educational centers of the Regnum Christi group are among the 100 best schools in Spain, according to the rankings of the newspapers El Mundo and El Español, for their innovative character, for the use of new technologies in teaching and for their international and differentiated training.

Being among the 100 best Spanish schools is not easy and achieving it for several years is even more complicated, but some Regnum Christi schools have achieved it once again in 2021. In the special 100 best schools published by the newspaper El Mundo, four Regnum Christi schools are positioned as the best educational centers: Everest School Monteclaro (Madrid), Highlands School Sevilla, Highlands School El Encinar (Madrid) and the school Real Monasterio de Santa Isabel de Barcelona. In addition, Cumbres School Valencia stands out in the ranking of the best private and charter schools of the Valencian Community

For the past five years, El Español has been selecting the most outstanding educational centers and, on this occasion, has also chosen as one of the 30 most innovative schools the Real Monasterio de Santa Isabel school in Barcelona for its comprehensive education, new ways of teaching and for incorporating ICTs in the classroom. In addition, this same newspaper has selected the 20 best international schools in Spain and has chosen two from the Regnum Christi group: Highlands School El Encinar (Madrid), for its excellent education and its international and individualized teaching; and the Highlands School Sevilla for teaching all subjects in English in the first years, incorporating French from the age of eight and for the markedly international nature of its teaching methodology
