Letters to Parents

Currently the main media used for school/teacher to parent communication is email, and the CHS Social Media Sites Facebook, Instagram, TikTok, Twitter, and Youtube.

Calendar of Events

All school wide events are published on the school's calendar which the students have direct access too. Parents can view the calendar on this website.

Permission Slips

CHS requires parents/guardians to authorize student participation in additional classes, or extra and co-curricula activities. Authorization is usually done with a permission slip. Permission slips are issued from the office or group coordinator (a teacher).


CHS will attempt to contact parents/guardians using the following phone numbers:

448-2916, 448-2917, 616-2916, and 616-2917

Please save those numbers so you may associate CHS with a missed call. A call from CHS may come from any of several offices, so when you return a call, please identify yourself and your daughter/ward (the student) so that your call may be better redirected. CHS does not receive SMS (text) messages on the 616 numbers.


Parents are expected to provided the school with email addresses to be able to receive notices. Email may come from the CHS Messaging System,, or any teacher or office; from a <user> Do not reply to the, and there is no need to reply to bulk email like notices and report cards with "Thanks", "Noted" etc. Also, check your junk mail and apply the appropriate settings to your email client to prevent CHS mail from being treated as Spam and Junk. Additionally, "Letters to Parents" and other messages are sent to all students at their CHS issued email accounts.

On becoming a CHS student, each student is provided with a Google Workspace for Education Account. Letters and notices to parents are usually sent to students as well. Students are expected to inform and remind parents of notices and upcoming events.

Parent/Student Site

The Parent/Student Site will provide updated information on:

  1. Student attendance.

  2. Section of the teachers' gradebook.

  3. Statement of Fees

  4. Timetable

The Parent/Student Site, a component of the Student Information System (SIS). Students are issued a Student Number and a Password which are needed to access the parent/student site. Parents should obtain those from the students and keep them in a safe place. CHS will not issue student number and password over the phone.

The information on the SIS is based on the data entered by CHS staff. If you have any question or need to query student marks, attendance or fees, please first do so through the student. Allow the student to clarify the entry, or to get the information from the teacher or office. This method usually allows a teacher to apprise the class as a group which is more efficient than individual conferences with parents.

Accessing the SIS

  1. Go to the website

  2. Click Log In and enter the student number and password issued to your daughter/ward.

  3. At a successful login, click on the link [Parent Main] which will take you back to the home/main page of the Parent/Student Site. From there you may select any one of; Attendance and Grades, Fees, and Timetable.

Here is a simplified guide to help better use the online gradebook.


Some rows have been numbered for better reference.

  • 1: Shows the Subject description and code.

  • 2: Group name. Items above are in this group.

  • 3: No mark assigned * (x/30). This assessment does not affect the student's average.

  • 4: Comment on above assessment Asn22

  • 5: Though 0.0% is displayed, no mark has been assigned (/15) and this assessment does not affect the student's average. The assessment has been created but the teacher has not yet entered the mark.

  • 6: Student obtained 0 marks out of a maximum of 15 marks (0/15). This results in 0.0%.

Report Card

CHS operates a three term school year. Reports are issues at the end of those three terms. Here are some sample sections of the report card.

Subject Block

The subject block gives details of that specific subject and the comments below the subject block are those of the subject teacher. See Work Ethics for details.

Average Block

  • Average is the unweighted average (arithmetic mean) of all the subjects, i.e. all subjects are equally weighted.

  • Grade uses the scale (I, II, III, P, U). See Grade Scales for details.

  • Demerits received for infractions during the term

Attendance Block

  • Days Open represents the days with scheduled classes.

  • Days Enrolled refer to the number of days the student is enrolled at the school. This may not differ from days open unless if the student transfers after the school year begins or ends.

  • Days Absent refer to both Excused and Unexcused Absent. As long as the student is not at the scheduled class, she is absent. 0.36 days absent for February, in the example, would mean 4 periods absent in an 11 period day (4/11 = 0.36).

  • Periods Late though would mainly imply days late (Assembly period/Period 1); however, includes late to class as well.

  • Attendance details are available on the Student/Parent Site of the Student information System.
