And you could make it a bit more compact by not creating variables that are used only once, and iterating on the student objects directly:
for (var stud of students ) {
var printOut = "<h1>" + stud.name + "</h1>";
printOut += "<p>Track: " + stud.track + "</p>";
printOut += "<p>Achievements: " + stud.achievements + "</p>";
printOut += "<p>Points: " + stud.points + "</p>";
print(printOut);
}
