I can add to education in Germany, also in Bayern!
In the last year of kindergarten (turning 6) the children have separate Vorschule classes. They do basic maths and writing and prepare them for school. The first two years of kindergarten is all play! My kids have Spielzeugtag - toy day - on Fridays and they all bring in their own toys to share and play with, it's really nice. Our kindergarten has 3 rooms, my DD's room has 25 kids and 3 carers.
Grundschule - primary school is 1st - 4th class. They start learning English in 3rd class, age 9 onwards.
School runs from 8am to up to 1pm. Some days my boys finish at 11:25 and are home by 12pm. That has taken some getting used to from the English system! They get the school bus to school, this is paid by the Stadt. There is also a walking bus for kids who live closer by.
They have 2-3 pieces of homework every day, usually a print out sheet or a page in a workbook.
1st Klasse has been a very slow start for my DS2, his homework so far has been writing pages of 1, 2, 3 etc over and over again! Then he has another book to practice letters in as well. Given he was writing small sentences in year R this has been a bit dull for him! We're explaining to him it's so everyone is at the same level.
2nd Klasse my DS1 is doing more writing and grammar then more complex maths
Children are sometimes held back a year if they don't progress well, and they are allowed to delay school start until age 7, especially if summer born.
Parents pay for all workbooks, (the different coloured plastic covers for the workbooks!!) pens, pencils, art supplies, various pads of paper, enormous school bags - everything! The list was given to us in the first week of term which ensured a nice rush in the shops! It's incredibly specific, you must not get it wrong! We also paid €40 per child to the school to pay for the photocopying for the year and 3 workbooks each. Kids also wear slippers in school! Which when you think about it makes total sense so you have no mucky shoes in the classroom.
In Bayern in the 4th Klasse my friends son is having weekly tests to determine his grade which will then decide on the type of school he can go to. All the tests count until January after which it's decision made and all the rest of the year is for fun. My DH grew up in Hesse where teachers and parents decided what type of school was better for the child.
Where you live has a set area for what school your child will go to. If you move to an area your child will be given a place in that school. If you move out of area you are expected to change schools unless you apply to be a 'guest' with a valid reason. There is also nothing like Ofsted so no real way of assessing whether the school is a 'good' school.
I don't know much about the secondary school system from age 10 but I do know children in Gymnasiums work to the Abitur (a level equivalent) and it is intense. Our 18 yr old babysitter speaks brilliant English. Certainly better than my Spanish after A Level!
Wow that was a bit epic!
