var html = '';

for (var i=0; i<students.length; i+=1) {
  student = students[i];
  html += '<h2>Student: ' + student.name +'</h2>';
  html += '<p>Track: ' + student.track +'</p>';
  html += '<p>Achievment: ' + student.achievments +'</p>';
  html += '<p>Points: ' + student.points +'</p>';
};

function print(html) {
  document.write(html);
}


print(html);

It's cool that you assigned the variable students to students[i]. That way you really can just access the property using just student

This alternative would work in the long run when you have a lot of properties and values in an object and could just make a change to that variable instead of tracking every single [i] in the object and changing it.

Good idea!
