If SLS homework will not submit, preserve the child’s work and record the exact error before refreshing or changing browser settings. Check whether the problem is uploading a file, completing an activity or accessing the assignment.
Punggol students should compare their file with SLS’s current upload requirements and use a supported browser. A completed worksheet on the device does not necessarily show that the teacher has received a submitted response.
If the deadline is close, tell the teacher promptly and ask what alternative submission is acceptable. This guide helps families troubleshoot the technical problem without losing the learning work or assuming that a failed upload automatically extends the deadline.
CHAPTER 1 OF 5
Identify the point of failure
Note the assignment name, activity or question and the action that fails. An error while attaching a photograph is different from an assignment that cannot be opened.
Use the official student assessment guides for the relevant response type. Follow the assignment’s instructions rather than assume every activity uses the same submission steps.
CHAPTER 2 OF 5
Keep a copy before troubleshooting
Retain the original file and any separately written answers. Where practical, record the visible error and the time it occurred, without sharing classmates’ information.
Before closing the page, check what work has been saved. A screenshot can help explain the problem, but it should not be treated as proof that SLS accepted the submission.
CHAPTER 3 OF 5
Check attachment requirements
The SLS upload guide lists accepted file types, size limits and image dimensions. Check the actual file rather than estimate its size from how many pages it contains.
The guide says valid uploads are scanned for viruses and large files may take longer. Allow the upload to finish and confirm that the intended attachment appears; avoid repeatedly adding the same file while an upload is still processing.
CHAPTER 4 OF 5
Use the current browser guidance
Check the current system and browser requirements. Older school handouts may list earlier versions.
The browser troubleshooting page discusses extensions, cookies, JavaScript and cache. Preserve the work first and use the guidance relevant to the error, rather than clear everything immediately.
CHAPTER 5 OF 5
Tell the teacher and use support appropriately
Send a concise report: the assignment, error, device or browser and steps already tried. Ask the teacher how to provide the work if the technical problem remains; do not assume an email attachment is accepted without checking.
The SLS Helpdesk page distinguishes login or account support from other technical issues and lists current contact hours. Keep the eventual submission confirmation so the family can close the task.
