So you would favour non religion over religion...
On a purely personal level I'd like education to be able to focus on something useful, but the state of the world is such that children need to be taught about some of the predominant religious viewpoints. I don't see a need for religious organisations to be involved in the running of schools, and certainly I object to religious organisations using them as tools of indoctrination. I advocate for religion not having preferential treatment.
.... and the answer to someone who questions religious representation must be yes
And, yet again, because you seem to have some sort of fetish for this particular straw man, no-one is arguing against the OPTION of religious representation - in schools or in the upper house of parliament - we're arguing against it being an institutional requirement.
But we know for instance that the backbone of the primary system at least are schools founded by religions.
Hardly the backbone, but there are certainly a number of schools which were founded by religious organisations, and many which are still funded by religious organisations and which operate within premises owned by religious organisations - none of which is a good argument for requiring them to be involved the educational or pastoral decisions of those schools.
Diocesan boards of Education are part of the repository of educational expertise.
At best, questionable. If particular individuals are, then by all means consider those individuals for a place, but that doesn't mandate the requirement that school boards have religious representation.
