He said the visit was intended to reassure parents and students ahead of the resumption of classes on Monday.
Among the measures being considered are the deployment of additional security personnel, construction of secure perimeter fencing, installation of more closed-circuit television (CCTV) cameras, and the establishment of a panic button system directly linked to law enforcement for faster emergency response.
Romualdez also met with teachers and expressed support for programs that would help address the emotional recovery, mental well-being, and overall welfare of students following the tragedy.
"We are also looking into improving the ambiance and atmosphere of classrooms and hallways to help restore a sense of normalcy, security, and comfort for our students as they gradually move forward from this difficult experience," Romualdez said.
He said the planned improvements would not be limited to San Jose National High School but would also be implemented in all 60 public elementary and high schools across Tacloban City.
"We will do everything we can to ensure that our schools remain safe spaces for learning, growth, and opportunity," he said.
Three students were killed and 21 others were injured in the 22 June shooting at San Jose National High School.
