According to the supreme court, what is the status of prayer in the public schools?

Our Father who art in Heaven,

Holy be thy name,

Thy Kingdom come

Thy will be done on Earth as it is in Heaven

Give us this day, our daily bread,

And forgive us our sins,

As we forgive those,

Who sin against us,

Do not bring us to the test

But deliever us from evil,

Amen.

I am not sure about this
