Can anybody tell me a good high school in dallas texas?

Where in Dallas? Parts of the city of Dallas are actually in other school districts, so it's impossible to advise you without more details.

Unlike some places in the country, in Dallas you have to attend a school determined by your home address, unless you attend a magnet school. Some locations in Dallas have an attendance zone that require you to attend a suburban school, outside the city of Dallas. Some Dallas schools don't have a very good record. The schools in the northern suburbs tend to be better, however you have to live in that attendant zone. So unless you plan to choose your address by which school is the best, you won't have much choice.

The Dallas School of Science & Engineering.

Best School is Yvonne A. Ewell Townview Magnet Center. It is a high school where they offer different kinds of "schools" or programs that wil focus in the part of subject from science and engineering to business management. It is national recognized school, and it offers great quality of education. It is located south of downtown Dallas in case you are not close to the school, there is bus service from many different DISD high schools that will pick up and drop off at the same school closer to where you might move. There are more good high schools in Dallas, just depends where you are going to live. Good Luck!
