AFAIK they are also taking a new stand on children's education. In the same article they write -
"As they grow, help them to do their best at school. Christian parents do well to research and apply Bible principles to help their children decide how to use education wisely."
They want parents to now actively assist in ensuring the kids are doing their best at school.
For many, this will be a new and added pressure as a JW. More time will need to be spent on home studies and with parents becoming involved with this.
My father, who was a very strict JW Elder, encouraged us to always do our best at school but didn't pressure us and he didn't spend any time helping us with home work or studying. If we had a problem, he would encourage us to talk to our teachers.
