Delcastle is a school where our children will graduate with a certificate in their career area. This will enable them to be able to find a job with a decent starting rate. I definately recommend this school. My son has done very well with his academics and in sports. The teachers are very helpful as well. I do feel that parent involvement could be better though. The teachers give students a day (Tuesday) to stay afterschool for extra help if needed. This is a plus...
