In mid-February, ten Alcides professors received workshops on digital teaching platforms held at the University of Puerto Rico at Mayagüez, Pontifical Catholic University of Puerto Rico at Mayagüez, and Interamerican University of Puerto Rico at Aguadilla. Alcides' chemistry teacher, Migda Ruiz López, collaborated in developing the high school chemistry module that was used during the COVID-19 pandemic. However, Alcides, as most public high schools, administered the Puerto Rico college admissions exams (PAA, for its initials in Spanish) in-person between 1–4 December. During February 2021, it was one of 172 public schools identified as "suitable to open" that formed part of an initial phase proposed by the department to resume in-person teaching starting in March. Nevertheless, this plan was abandoned, and in-person classes did not occur until 13 May.
