Quick analysis based on the PARCC scores by ethnicity below.

First, here are the reported percentages of L4+ in ELA and MATH at Hardy and Deal in 2016:
Hardy 2016 ELA: 40%
Hardy 2016 MATH: 31%
Deal 2016 ELA: 63%
Deal 2016 MATH: 50%

If Hardy had the same demographic composition as Deal, its scores would be 51% in ELA and 43% in MATH in 2016.

For reference, here are the reported 2015 scores:
Hardy 2015 ELA: 24%
Hardy 2015 MATH: 22%
Deal 2015 ELA: 68%
Deal 2015 MATH: 44%

If Hardy had the same demographic composition as Deal for the 2015 year, its scores would be 30.5% in ELA and 31.1% in MATH.

These numbers strongly suggest the gap between Hardy and Deal is shrinking rapidly.

The demographics-adjusted gap between Deal and Hardy in 2015 was 37.5% (=68%-30.5%) in ELA and 12.9% (=44%-31.1%) in MATH. In 2016, these gaps have shrunk to 12% in ELA and 7% in MATH.

Stated again for emphasis, in one year, the ELA gap shrank from 37.5% to 12% and the MATH gap shrank from 12.9% to 7%. I believe strongly this gap will all but vanish within two years. [/quote]

Hary was a solid school 2-3 years ago (and before that too) - but the rapid demographic changes are probably what is responsible for quickly closing the gap.  This will probably build on itself - more IB students results in more IB students - until the gap is gone.   Good teachers + good demographics = good scores.[/quote]
