Janh, sorry I didn't reply, but I went to bed! 
Yes, that is the plan. Sometimes it doesn't work....for an example if two kids don't get on and one has to be moved out of the class, if teachers leave the school/ go on maternity leave. You don't always get to be a form tutor when they enter the sixth form, since there are fewer classes.
But the plan is that you stick with them....sensibe since you get to know them and their families.
We have a review day once a year and each child will also get a standard parents evening a year. THis works out as 4 parents evenings for us, and separate ones for the sixth form.
Parents can (and do) also make appointments to see the form tutor/director of studies. Shhing subject teachers outside of parents evening is less comon, but I have spoken to several on the phone over issues.
I can understand the feeling of 'lack of contact' that parents must have. I'll feel it myself when mine go to secondary. The thing is that in secondatry teachers work with so many kids. I only work part time and I teach around 160 kids ...and that doesn't count the 28 I am form tutor for,
Parents often seem to forget that I am also a teacher as well as a form tutor, so I can't go and look in the changing rooms for x's kit, go round all Y's teachers and get replacement books, stick with z in lessons and make ure he collects all his stuff (all of which I have been asked to do this year
)
