Coursework should be submitted only from those courses that have been assigned by CLASS; supplemental schoolwork, courses from other institutions, and work not specifically required by the course instructions should not be submitted. If you desire to submit high school level transcripts of courses completed outside of CLASS, send them under separate cover to the attention of our Transcript Department.
Do not submit any other correspondence with your coursework. Letters and payments sent with work for grading will be delayed at best. Go to How the Grading Process Works to see how coursework is handled.
We recommend you mail completed tests about once a month (and daily work as courses are completed) to minimize postage costs as well as the effect of a possible mail loss. If you are approaching the end of a CLASS quarter, make sure your package is postmarked by the quarter ending date. Work postmarked after a quarter ending date will processed in the subsequent quarter.
Do not submit incomplete tests, daily work, or R&I sheets. Incomplete tests will be graded “as is” with the blank questions or sections being marked wrong. Daily work that has been partially completed will, in most instances, be graded “as is” with the incomplete sections marked wrong (in select cases, we may return the incomplete daily work to you). If an R&I sheet is received without its required work attached, the R&I sheet will be returned to you. In courses that do not require the submission of daily work, the R&I you submit must include your daily work score. If such an R&I is submitted without the daily work score, it will be returned to you.
If you are mailing both tests and daily work at the same time, place them in separate envelopes. Write TESTS on the envelope containing the tests and DAILY WORK on the envelope containing the daily assignments and R&I sheets. These envelopes can then be placed together into your mailing package, which should be sent to:
Attn: Grading Department
502 West Euclid Avenue
Arlington Heights, Illinois 60004-5402
If you have multiple students, you may mail their work together in the same package.
To make sure your work is graded in a timely manner, please DO NOT address it to Christian Liberty Press or CLP
Do not change or correct answers on a test before submitting it to CLASS. You may review completed tests with your student, but do not make any marks or alterations on a test once your student has completed it and given it to you.
For each non-scannable test, attach a Student ID label and write the course name and test number on the top if that information is not already included on the test. Do not use a Student ID label or place any stray marks on a pre-identified (scannable) test. Do not write additional comments on pre-identified tests.
Staple all pages of a non-scannable test together. Do not staple two or more tests together.
Do not attach R&I sheets when submitting tests. R&I sheets are for daily work only.
Make sure the tests you are submitting for each course are not mixed with the tests of other courses; keep each course separate in the envelope. This will speed up our handling process and reduce the possibility of any errors.
Submit only the original tests received with your curriculum. Do not submit photocopies. You should, however, make copies of your tests for your own records and for protection against mail loss. CLASS is not responsible for missing tests.
If a test you have submitted was postmarked by the quarter ending date, but does not appear on your student’s report card for that quarter, fill out a Report Card Adjustment Request Form. Staple your photocopy of the test to the form, and mail it to CLASS within forty-five (45) days (sixty  days if you have a foreign address) of the date we mailed the report card. We will accept photocopies only if the original you have submitted is missing. If you do not have a copy of the missing test, we may require your student to retake the test.
Submitting Daily Work and R&Is
Some courses require you to submit all written daily work with the R&I sheet when the course is completed, while others require you to send in a completed R&I sheet only. Please read the instructions for each course carefully to determine whether you are required to include daily work with the R&I sheet.
As your student completes a course, you should have been grading his daily work assignments on a regular basis. Before submitting the R&I sheet, calculate the final daily work score according to the guidelines in the course instructions and Making the Grade.
If you have misplaced an R&I sheet, you may request a replacement or use our downloadable/printable Generic R&I. If you are using the latter, make sure all fields are appropriately filled out.
Courses That Require Daily Work Submission
Do not alter the answers on your student’s daily work before submitting it to CLASS.
Before submission, attach the appropriate R&I sheet to the front of the completed daily work. Do not submit partial or incomplete daily work (exception, see Kindergarten below).
We recommend that you place a Student ID label on each of the first few pages of your student’s daily work or workbook in the event it becomes separated from the R&I sheet.
Make sure the daily work you are submitting for each course is not mixed with the daily work of other courses; keep each course separate in the envelope. This will speed up our handling process and reduce the possibility of any errors.
When preparing to submit your daily work, use a box designed for mailing. Pack the daily work first, then fill any remaining space with newspaper or other packing material that will prevent crushing or bursting which could damage your work. Seal the box using plenty of strong packing tape. Do not submit work in shoe boxes, small appliance boxes, or any other box not specifically designed for mailing.
CLASS is not responsible for missing daily work. If submitted daily work was postmarked by the quarter ending date but does not appear on your student’s report card for that quarter, fill out a Report Card Adjustment Request Form. Submit this form within forty-five (45) days (sixty  days if you have a foreign address) of the date we mailed the report card. If the daily work is missing, we may require your student to complete a make-up assignment, at the discretion of CLASS, to receive a final grade.
Courses That Do Not Require Daily Work Submission
Make sure the R&I sheet is appropriately signed. For grades 1–6, only your signature is required. For grades 7–12, both you and your student must sign the R&I sheet.
If an R&I sheet you submitted was postmarked by the quarter ending date, but does not appear on your student’s report card for that quarter, fill out a Report Card Adjustment Request Form. Staple your photocopy of the R&I sheet to the form, and mail it to CLASS within forty-five (45) days (sixty  days if you have a foreign address) of the date we mailed the report card. We will accept photocopies only if the original you have submitted is missing. If you do not have a copy of a missing R&I sheet, we can send you a replacement or you may use our downloadable/printable Generic R&I. If you are using the latter, make sure all fields are appropriately filled out.
Do not grade your own book reports. We will grade them for you. For seventh and eighth graders, the average grade for the two reports will be the final grade. For high schoolers, the two literature book reports will constitute twenty percent of the final grade.
List the book titles on the appropriate R&I sheet and make sure a Student ID label is affixed to the front of each book report. Submit both reports together, with the R&I sheet attached.
This packet can be included with any other daily work materials you are submitting.
When submitting your research paper and R&I sheet, also include the outline and the works cited page (a listing of those works represented and properly documented within the paper itself).
In addition, high school students will be expected to include hard copies of the pages from their source materials which they have cited in the body of their papers. For questions concerning copyright issues related to making copies for academic reasons, see copyright concerns.
After Kindergarten is completed, select a sample of 15-20% of the student’s daily written work. Your sample should include 15-20% of each course for which written work was required.
We recommend that you place a Student ID label on each of the first few pages of your student’s daily work in the event it becomes separated from the R&I sheet.
Attach the completed R&I sheet to the sample selection and send the entire packet to CLASS.
Verification of Receipt
We recommend that you return schoolwork by first-class mail. To receive verification of coursework having been received by CLASS, include a self-addressed stamped envelope or postcard in your package. We will mail this back to you when your package is opened. Although we cannot verify receipt of every item in your mailing, we can verify the date that your package arrived.
