Hi everyone, I am a parent of a 13 year old and I feel like I am losing my mind a little. My son has been forgetting his school assignments constantly. Last week I found out he had a science project due the next morning that he had not even started. I was literally up until midnight cutting out pictures from magazines and gluing stuff on a poster board while he slept. I do not even know how that became my project.
I started checking his bag every night and found THREE worksheets he had stuffed at the bottom, all past due. His teacher emailed me saying he is smart but seems disorganized. That email honestly stung a little.
What is the best way to handle this? Has anyone been through this? I feel like I am failing as a parent but also like I am doing too much at the same time. Any advice would be appreciated 
Oh wow, the midnight poster board moment hit me right in the chest because I have been THERE. My daughter did the exact same thing in 7th grade and I remember hot gluing a volcano model at 11:45 PM on a school night. What I can tell you is that the solution is not doing it for them, even though every parenting instinct says otherwise.
What worked for us was a simple Sunday check in. Every Sunday evening, we sat together for maybe 15 minutes, opened her planner, and wrote down everything due that week with the dates. No phones, no TV, just us and the planner. Within a month she started doing it on her own without me even asking. Kids this age are not being lazy, their brains are just genuinely not wired yet to think ahead. They live in the present moment like it is a superpower and a flaw at the same time 
Not to be that person but… did anyone else notice the parent said the kid slept while THEY finished the project? That right there might be part of the issue I say this with zero judgment because I get it, watching your kid fail feels awful. But kids learn more from turning in an incomplete project and facing the teacher than from having a perfect one their parent made.
My son forgot a book report once and I let him go in empty handed. He was mortified. He has not forgotten one since. Sometimes the natural result of a thing is the best lesson. Just something worth sitting with.
GlassTech makes a fair point and I agree with that approach for older teens but for a 13 year old who is still figuring things out, I think a mix of support and accountability works better than going cold turkey on help.
What we did with our son was set up a shared Google calendar. Every Sunday he types in his assignments for the week and I can see it on my phone. If something is not on there by Sunday night I ask about it. It takes the daily nagging out of the picture completely because he knows I can see the calendar. He started being more proactive just because he did not want me checking in on him every day. Works like magic honestly.
I work as a school counselor so I see this from the other side every single day. What you described is extremely common at this age. The prefrontal cortex, which handles planning and organization, is literally still developing through the mid 20s. So when your kid forgets assignments it is not attitude, it is biology.
That said, here are a few things that genuinely help. First, have the child write assignments down the moment they are given, not when they get home. Second, create a homework spot that is the same place every day, somewhere visible and not in their bedroom. Third, break big assignments into smaller steps with mini deadlines. The science project probably felt too big to start so he avoided it until it was a crisis. That avoidance cycle is really common at 13.
DroidPro said it perfectly. I want to add something from my own experience as a mom of three. The homework spot thing is underrated. My middle child used to do homework in his room and I had no idea if he was actually working or watching YouTube. Once I moved homework time to the kitchen table, everything changed. I could see him, he could see me cooking or cleaning, and somehow just having another human nearby made him more focused.
Also can we talk about how the teacher said he is smart but disorganized? That is actually a good sign. It means the problem is not ability, it is systems. You just need to help him build systems that work for HIM. Not every kid works the same way. Some need visual reminders, some need timers, some need a checklist they physically tick off. Try a few things and see what sticks 
Okay I am going to be the sarcastic one here since someone has to do it. So let me get this straight. The child forgot the project, went to sleep peacefully, and woke up to a completed poster board. And now we are asking why he keeps forgetting assignments? I am not trying to be mean, I genuinely laughed because I did the exact same thing for my daughter twice before my husband looked at me and said “who is learning here exactly?”
The uncomfortable truth is that sometimes we make it too easy for them to forget. If there are no real results then there is no real motivation to change. I started letting my daughter handle the awkward conversation with her teacher herself when she forgot something. That was more effective than any planner or app I ever tried.
LinkRead and GlassTech both touched on something important. Natural results are powerful. But I want to add a practical middle ground for parents who are not quite ready to go full hands off.
Try what I call the “remind once” rule. You remind them once about an assignment, you do not follow up again. If it gets done, great. If it does not, they deal with the teacher. You are not the assignment police and you are not their secretary. You are their parent. Once my kids understood that I was only going to say something once, they started listening the first time. Took about two weeks to adjust and then it clicked. Also getting them a physical wall calendar they write on themselves is surprisingly effective, there is something about writing with a pen that makes things stick more than typing.
Can I ask something? How much sleep is your son getting? I know that sounds off topic but I am asking because my son had the exact same issue and after months of trying planners, apps, reward charts, everything, we figured out he was only getting about 5 to 6 hours of sleep on school nights because he was on his phone until late. Once we moved phone charging to the kitchen at 9 PM, his focus at school improved within two weeks and the forgotten assignments dropped dramatically.
Sleep affects memory consolidation, attention, and planning ability in a big way for teenagers. His brain might genuinely not be retaining the information about assignments because it is running on empty. Just worth checking before assuming it is purely an organization problem
