Change your while to this:

while ($row = mysqli_fetch_assoc($fetch)) {
    $row_array[$row['school_name']]['school_name'] = $row['school_name'];
    $row_array[$row['school_name']]['terms']['term_name'] = $row['term_name'];
    $row_array[$row['school_name']]['terms']['department_name'][] = array(
        'department_name' => $row['department_name'],
        'department_code' => $row['department_code']
    );
}

Probably it's not an effective program, but it should gives you best result. Hope it helps :)
