This was a slightly older post, but my sons went to school in NMUSD near Newport Coast and now attend in Irvine. The two districts cannot even be compared beyond the elementary schools! My sons attended school in Newport & Eastside Costa Mesa - the elementary’s (specifically Woodland Elem = Kinder-2nd Grade, Kaiser Elem = 3rd Grade - 6th Grade) were GREAT! They have an “Art Masters” art program that brings in college level instruction, the parents are VERY involved and the PTA is well supported which seems to equal excellent after-school programs.
However, once they get to the Junior High and higher level, the Newport Coast parents mostly put their children into private school. The ones that are left are primarily the party-parents (i.e. the ones that milked their HELOCs to impress their friends and are now working 2-3 jobs IF they still have their homes) who do not pay much attention to their kids and hand them cash to keep them busy and out of their hair. My oldest son actually BEGGED me to transfer him (when discussing the merits of Irvine vs. Costa Mesa, as we had been in Irvine previously) and said “Mom, I know kids do drugs everywhere, but the kids I know in CM are making bad choices, and the ones I know in Irvine aren’t!”
I have friends with High School-aged children and many have either moved, or their kids are in OSHA. The other few (who attend Newport Harbor) are kept EXTREMELY busy between sailing (if your children are into sailing, then this area may be worth consideration, the Newport Harbor program is AMAZING!) and other sports so that they do not have time to get into trouble. Much of it will depend on the personality of your children too, so be brutally honest with yourself. My youngest son will go anyplace and excel, my older son is an above-average student, but his social standing is a major deal to him, so that took me back to Irvine in a hot second! Hope that helps!
