I was adopted when I was 15 months old and I have lived with my adoptive parents since. I am sure that my school knew about this since it was probably something my parents had to legally inform them about. Also, I can remember my deputy-headteacher once having a meeting with me about this saying, 'you're entitled to this support because you're adopted'. The support he was referring to was in relation to a bursary.
I asked my adoptive father about what my school used to do for me because I was adopted and he said something along the lines of 'they kept a close eye on you', meaning that they monitored me. And I suppose to some extent this may be true as the Head of Sixth Form would often call me into his office to catch-up and ask how I was progressing even though I had really high grades and good behaviour and some of my classroom teachers would report to my Head of Sixth Form about how I was in class in terms of concentration, performance etc even though it wasn't like I was doing badly and they had to monitor me for that reason.
I can understand senior members of the school like the deputy-headteacher knowing but I was shocked when one day in Year 13, my history teacher, who had only been there for a year and was a Head of Year but Head of Year 8 and so had nothing to do with me beyond teaching me said 'So, you're adopted, is that right?'. She said this in a casual, inquisitive way as she was quite nosy but also we got along since there were only two people in our history class for all of A-level and we were her first A-level students at the school ever. She had previously gossiped to us about her private life and about teachers she didn't like or had tensions with and complained about the headteacher so I'm not surprised by her asking this question of me so invasively. But, I want to know how she was even able to ask it and how it was more so an assertion so she knew I was adopted and just confirming as though she had just found out rather than not knowing and just asking. Maybe all of my class teachers had to 'look out for me' because maybe adopted students are treated as special by the government due to having been in care (not that I'm sure of this) so maybe she was told about this by the senior team but that seems unlikely as she would have been the sort to ask me at the beginning of Year 12.
I think what's more likely is that on parents' evening in Year 13, my parents didn't show up because they were busy but my teacher had to essentially confirm with the headteacher that they were not going to come so she could go home (my history teacher was complaining that the head was insistent that the teachers couldn't leave until they were sure parents wouldn't be coming). Maybe when discussing my parents someone may have said 'that student is adopted' and she may have picked up on that although I am not sure otherwise how could she know? Are teachers really prone to gossip about such personal matters for a student?
I had three history teachers for A-Level - the other two taught me since Year 7 - and they never asked about this although I am not sure, again, if any normal teachers would know about this so they might have known but just not mentioned it.
So, in summary, how did my history teacher find out about this and is it true adopted children are 'looked out for' at school by the teachers?
Also, I never really talked to my headteacher as she managed the school while the deputy heads managed more specific things like pastoral which is why it was the deputy head who told me that I was adopted (even though I already knew). Yet despite this lack of contact with my headteacher she seemed to know about me much more than other students: she knew my full name, she would greet me in the corridors etc. Yes, I had been there since Year 7, but how would she know me so well unless because I was adopted she would have been briefed on me. Even when I was in Year 7 she seemed to know me on such a good basis although I didn't cross paths with her much - it wasn't like I was volunteering for her groups or something like that. So, how likely is it that my headteacher knew I was adopted although she never mentioned it?
