Everybody has told you how to sort (college, then id), but nobody told you to USE STRICT!!! ;)

Now, some handy short-cuts in Perl programming:

Instead of using the ternery operator twice on each column for each row, you could just handle empty columns in the first check: 

$student_name = (defined $row[1]) ? $row[1] : ' ';
$student_blah = .... ad naseum

Or you could avoid all that extra typing by utilizing map: 
while (my @row = $sth_report->fetchrow_array) {
   @row = map { $_ || ' ' } @row;

   # .... rest of code
}

Also,the only variable you need is one to store the college (actually, you don't even need that one either! :D) ... the rest can be kept in @row, which can be then stored in a hash whose keys are the colleges, and whose values are the rows of the students (ordered by id) who belong to that college: 
my %college;
while (my @row = $sth_report->fetchrow_array) {
   @row = map { $_ || ' ' } @row;
   my $college = pop @row;
  
   push $college{$college}, [@row];
}

[download]
And some code to print it back out: 
foreach my $college (keys %college) {
    print "$college:\n";
    foreach my $row (@{$college{$college}}) {
        print "\t", join(', ', @$row),"\n";
    }
}

Hope this helps. :)
