Schools

I don’t republish unofficial school scores. For South Brunswick, start with the New Jersey Department of Education’s School Performance Reports, then confirm the exact school assignment for any address with the district, since some NJ towns send students to regional or neighboring high schools.

My take for buyers, sellers and renters

• Buyers: a below-county-median effective tax rate stretches your budget further here than in many Middlesex towns. Compare with the town comparison tool.
• Sellers: with fewer public market indexes for South Brunswick, a comparable-sales analysis matters more. Get a free home value.
