The answer to this question is going to vary student to student. 100% of the time if there is a student that you believe is falling behind then that student should receive extra support. Depending on the situation, if it's not something you can handle on your own as a teacher, reach out to your team and/or supervisor for suggestions and help. If you believe the student may be in need of ESE services, you should also reach out to the appropriate people in your school to get testing and services if necessary.

I would offer them tutoring opportunities and also reach out to the parents to see if there is extra support they can get at home.

I would start by having a conversation with the student about why I feel they are falling behind in class. There may be a simple explanation as to why before possibly needing to recommend the student to a different classroom. Every student learns uniquely, and because of this, sometimes all they need is additional help and attention. Student's can often feel an immense amount of stress and pressure from the amount of work and responsibilities they have to manage. If something bigger is going on to affect the student, you are now informed of the situation and can connect them with the appropriate resources.

Giving them some help in encouraging them to finish their assignments is important to consider. Additionally, maybe excusing one assignment to show them you care and encourage them to catch up can help them.

Maintain open communication with the student, parents, and any other relevant stakeholders. Discuss concerns, observations, and potential interventions. Collaborate with parents to gather insights into the student's needs and strengths.
