I wouldn’t recommend anyone go into teaching unless they really want to teach.
Thinking working with children is ‘fun’ isn’t enough.
‘Loving’ your subject isn’t enough.
Thinking it’s handy because you won’t need childcare in August isn’t enough.
My PGCE was hard and I was 21 with no kids and a boyfriend that did all the cooking and cleaning! I was in at 7.45, home at 6, planned all evening and wrote essays all weekend. I also caught every bug going which knocked me for six. The NQT was probably even harder as I had responsibility for my own class and then year after was harder as I lost all the non contact time, and got given subjects to coordinate (small school) with no extra pay! Then it got nice for quite a few years, until things got really awful. Round about 2010…
My hours now are similar to my training hours really even at 25 years in, though I get in at 7.20 as it’s quiet at the printer!
I don’t think I could have done it with small children without DH who could work flexibly or my parents who live round the corner and were retired.
On top of covering those basic hours, have a think about what you will do if…
Your child is unwell. We get time at my school if our child is seriously unwell (eg in hospital) but for anything routine like chickenpox, it’s unpaid. DH did all illness childcare when ours were young.
Assemblies/sports day/plays/medical appointments. My parents or DH did all of these. I didn’t ever attend one on a day that I worked (I was part time so attended some).
Snow days/inset days-my DC nearly always closed when mine stayed open. DH did all of these.
Expectations at your own school-evening concerts, parents evenings, open days. All of these were 4-7/8 at my school. Again, DH covered them all.
Breakfast club at their school was no good as it didn’t start till 7.45 and my school was too far away to get to. They have no after school clubs either.
Think carefully why you want to teach and how you will juggle the childcare. Then if you think that’s all doable, get a week or two shadowing in a school.
