Here's an interesting map a TCU Professor put together mapping US neighborhoods to educational achievement.

For Denver, it's striking seeing the North/South divide. It's even greater than I anticipated.
Also, you can very much see the trend many demographers have talked about for cities like Denver: A thriving city core, "inner ring" suburbs in the state of some decline, having lost their competitive edge, and then outer ring suburbs that rival or exceed the educational attainment of the core city (though in Denver's case, the number of graduate degrees in much of the core of the city is pretty impressive and matches up with any of the even outer core 'burbs).
I remember reading an article a few years back about the declining older suburbs. The author made the point these were often 1950s-70s built up areas, with low quality housing stock and none of the amenities of the urban core (much better architecture, parks, cultural facilities, sports facilities) and those areas were having the greatest difficulty staying competitive. For Denver, that probably includes large parts of Aurora and the old Northern suburbs, and parts of the Western burbs.
It's interesting to consider how things have changed in last 5- 7 years, and how they are changing. Obviously, Denver itself is undergoing massive gentrification which will only accelerate the trends noted in the maps. The southern suburbs - with jobs + quality housing stock will continue to thrive. Select parts of the older suburbs are doing okay too (parts of Arvada comes to mind). Broomfield and Boulder are in their own submarket category and are thriving.
