HOUSTON (KIAH) -- Superintendent Mike Miles of the Houston Independent School District joined CW39 in our studio to address many parent comments and concerns. Some of the big topics that were discussed were the $4.4 billion bond election, teacher and staff turnover, just to name a few. According to the HISD website, the bond will work to improve items such as increase security, HVAC systems and expansions of campuses. "It will not raise taxes, that's what I want to say at the start, but we haven't had a bond in the city since 2012 for HISD, and that was a high school bond," Miles explained. "So, we built mostly high schools, and then we haven't had for elementary and middle since 2007 so there's a lot of facility needs, a lot of our HVAC systems, air conditioning and cooling systems, our security, perimeter fencing, single point of entry, but imagine that you have a house and you haven't repaired the fence or the hot water heater or the faucets or the pipes or the sprinkler system your roof over." Since the bond proposal was introduced, many parents disagreed with it or not trusting Miles to handle billions of taxpayer money. Miles added, "We have a billion dollars for pre-K and career tech ed facilities, so we upgrade our skills for our students, and then we have the rest two and a half billion for facilities like new builds, expansions." Miles also talked about turnover after several community leaders, parents and staff reported sudden staff changes since HISD became under the superintendent's leadership. In response, Miles said that they started the school year off with 28 vacancies out of 10,640 teacher positions. "We feel really good about the staff that we have now. Last year, we had some more teachers leave than years past, many of them we asked to resign or to move and we think that's okay," Miles said. "We think that it's great that we have a staff that are really hitting the ground hard for our kids. We have a principal corps that's ready to go. So, this year has been a pretty good year so far as far as teacher effectiveness, and we're going to continue to do that, so we're going to grow that capacity over time." Since the takeover, The New Education System, or NES, has been debated since the start of the takeover. Parents told CW39 that the transition has been difficult on their children. However, Miles says that NES has been a positive for the district. "NES has been undeniably a success. We went from 93 A and B rated schools to 170and then we went from 120 1 D and F schools to 41 D and F schools, and most of the struggling campuses were NES and so there's, there's been a great improvement and now, the whole district does not need to be NES as we have 130 new Education System schools today, and the most we will have is probably around 150 over the long haul," Miles said.
