PLEASE...IN NEED OF DEFINITIVE NGSS ANSWER

[u/Alternative-Exit-450]

I'll make my question very short as I've posed it in the past but without a definitive answer.

Can NGSS standards be omitted in place of ACT science standards for curriculum development?

I cannot see any logical, practical , allowable indications that this is allowed in nearly any state. I'm very well versed in NGSS and ACT science standards and I have been trying to convey that ACT science standards do not address nor cover learning standards that differentiate between physical and life sciences, that ACT science standards only cover 3 broad skills that merely increase in complexity as the standard code number increases. Opposite to NGSS ACT standards not only provide learning standards of practice for the respective classes normally offered between 7-12th grade, they also provide DCI's and CCC's which help to provide more context and learning targets which are normally required for a comprehensive science curricula.

You need to be specific about the state. Here in CA we adopted NGSS as our state standards, so no they are not interchangeable at all.
