When Fr Joseph Kallepallil, SJ was transferred to Loyola School Mukundara in 2017 with a similar mission, he was replaced by Fr Jose Pulinthanath S.J. And Fr.Roy Alex joined as the Vice-Principal of CBSE School.
The Devassy-Jose duo deserves special mention for preserving everything as good as ever and adding to the existing facilities. Providing large-wing fans and a first rate public address system in the Indoor Stadium, sunshades on both sides of the cafeteria, furniture comprising wooden seat on stainless steel frame in the junior school classrooms, CCTV in all the classrooms and corridors, renovation of the Physics lab in the CBSE wing, completion of the school bus fleet renewal with 14 routes, widening the dangerous stretch of road near the main gate and putting up a retention wall along its side for additional protection, erecting the new school gate when the old one got damaged, thorough repairing of the fence around the ground, renovating the pavilion with a sunshade and tiling its floor, adding new seating facilities around the ground and repairing the gutters, a new playground exclusively for the UKG kids, putting up a truss and creating further space for indoor games in the third block of the ICSE building, and renovating the canteen are among the infrastructure development of this period.
A few major changes during this period were the discontinuation of the HSE stream, the introduction of the Prefect system, and the scrapping of LA Fest which was replaced by LOUD (Loyola Union Debate).
The period is also noted for its academic glitter. Between 2016 and 2020, the number of students appearing for the ICSE exam was doubled and still the record of 100% Distinctions could be maintained. The ISC results too have been as good as ever.
Fr. Devassy Paul was replaced by Fr.P.T. Joseph as the Principal on June 1st 2020.
