The point at which a learner is receptive to what is to be learned. This will differ from learner to learner and be dependent on a number of factors, including level of maturity, prior learning, and motivation. It is most commonly used in relation to teaching reading, in the phrase reading readiness. The concept of readiness includes the notion that it may be counterproductive to coerce a child into learning before they are ready. Teachers and educationalists are by no means unanimous on this point, many arguing that readiness can be achieved through the teaching and learning process and is not a point arrived at passively simply by waiting. The idea that children go through a series of stages which correspond with their state of readiness for certain types of learning has been underpinned in the past by reference to Piaget's work on stages. More recently, however, this concept of development in fixed stages has been widely questioned.
