		The individual teachers' scores on this teacher quality measure likely reflect those individual teachers' actual teacher quality.

		Overall, the measure captures teacher quality in a way that is best reflective of teacher quality as universally defined by educators.
		Overall, the measure captures teacher quality in a way that produces scores consistent with the way teacher quality was defined by the people who created the measure and/or tested the measure.
