Nothing offensive about it at all. If you went to the trouble of reading the analysis to which I referred you would know that.
The per cent mark remained lower for the three secondary school types: Comprehensive (estimate = -0.70, SE = 0.19, t = -3.63, p< 0.001);
State grammar (estimate = -0.98, SE = 0.19, t = -5.22, p< 0.001);
State other (estimate = -0.87, SE = 0.20, t = -4.32, p< 0.001).
The per cent mark remained lower for the four disability groups:
Cognitive or learning difficulties (estimate = -0.88, SE = 0.33, t = -2.67, p< 0.01);
Mental health condition (estimate = -3.00, SE = 0.44, t = -6.88, p< 0.001);
Other or multiple impairments (estimate = -2.20, SE = 0.55, t = -0.40, p< 0.001);
Social or communication impairment (estimate = -4.73, SE = 0.77, t = -6.15, p< 0.001).
