just clarifying a few things in this thread ... it is my understanding that if you have a CHILD IN THE SCHOOL .. you do not need a blue card to help ...
if you are a grandparent of a child .. you need a blue card
if you are a sibling of a child - and you are over 18 ... you need a blue card
if you are a sibling of a child and under 18 you do not need a blue card
if you are a parent of a child currently enrolled in the school - there is no rule stating that you need a blue card if you are volunteering..
to my knowledge. .. they are the rules.
Regarding your situation .. I do understand your wariness ... and your fear for your children ..
HOWEVER .. imo teacher and child ... teacher aide and child .. or parent helper and child should not ever be in a room alone together .. as a teacher I aim to not be alone with a child .. purely to cover myself should any questions arise as to why I'm with them. (does that make sense?) I'm a big fan of open rooms- doors open .. and staff being able to see each other and what they are doing at all times
I know that last year when my oldest son was in prep .. I would help out in the classroom - and other parents would too ... doing reading and sight words and other testing/ practice .. but they did those things IN the room with the teacher supervising.
I would think it rather inappropriate for a parent helper to take children away from the teacher supervision at any time ..
teachers and teacher aides all have police checks done - I know that teachers are checked annually .. I as a teacher wouldn't ask any child to work with a parent helper in a setting where I couldn't see them.
I dont think it would hurt for you to have a chat to your child's teacher regarding your own concerns ... follow your gut and do what you think is right to do
