What is bringing her to Dallas? I would suggest to stay out of Dallas ISD. The schools are horrid. There might be one or 2 not in trouble. A LOT of children who live in Dallas go to the private schools.
If she got a job in Highland Park that is another story. Highland Park is the VERY nice area and very expensive. IF the Plano schools were not as good as they are, our daughter would be in either Highland Park or private schooled.
The best school districts are outside of Dallas. We are in Plano for a reason.... schools. I am biased so please have her check all the sites to get a good feel for all the districts. www.greatschools.com The Allen and Frisco schools are good. The ONLY thing I don't care for about Allen is the size of the high school, it is just too big. Plus they (we since my physical address is Allen and I am Plano school district) are paying off the $60 Million stadium they just completed and started using this year. Hoewever their curriculum and overall schools are good. I don't know much about McKinney schools. I've heard good things about Coppell, Keller and Southlake.
Just make sure she does a LOT of research.
Does she have to be working 100% of the time from day 1? If not, she soulc substitute at a lot of schools and get a feel for how things are run before she makes a committment.
I substitute at the same elementary in Plano where my daughter attended 10+ years now. My daughter is a Senior at Plano West (in the top 1% of high schools in America per newsweek..) GREAT school.
She could easily live in uptown, experience the Katy Trail, White Rock Lake area, Arboretum, etc and commute. The single teachers I work with do live in the uptown area and love it.
There is a lot to do here and we've loved it from day 1 in 1989. Great restaurants, events, etc.
I hope your neice loves it here as well!
