I’m in the U.S. my dd is in a wealthy school district. Each school has multiple support staff and I can’t imagine a school without them.
we have nurses. They handle all the complex medical issues for students. I meet with ours annually to discuss my DD’s asthma. They also deal with skinned knees and tummy aches as they arise.
we have counselors. The number varies by school so that there are enough for each student. They handle day to day stress. They can provide small amounts of therapy. They also curate each child’s educational program as they get older.
some school’s have social workers. Most of ours the social workers are responsible for more than one school so they rotate through the week. That is because there are not enough children at one school to qualify for services. They make sure children and families are connected to benefit programs and just generally support children in need.
Every school has a special needs classroom and team. I don’t know the qualifications of all of these staff, but I know that there is at least 1 rotating educational psychologist in the mix at the elementary level.
what we don’t have. Teachers don’t have TAs as a general thing. There is often another adult in the classroom in lower years, but that is because students may have 1:1 aides or 1:2 aides. Those adults contribute to the general level of supervision, but they really are there to support their students, not to manage the classroom.
basically, the professional support staff is large and just as important as the teaching staff. I know there are school districts that have eliminated the support staff, but that is just crazy. I can’t even see how a school could run effectively. I know we have ridiculous privilege to send our dd to the school she attends but it should be the standard.
