Several subjects drag its grade down. Cost of living is its weak spot (D): at the median price, a 70 m² home costs 8.8 times the median annual income per consumption unit in the intercommunality. It lags on schools as well (D): bac results 4.1 points below the expected rate; brevet results 3.5 points below the expected rate.

The overall grade lands at D−, #65 of 73 in Val-d'Oise. On that grade it does better than 3% of compared French towns.
