seems natural. It is therefore difficult to fully understand the history of “improvement” as a concept and to appreciate that it was a genuinely new way of thinking in the early modern period. Furthermore, in contemporary use, the notion of “improvement” is assumed to be positive. This assumption has limited the critical attention given to the history of the idea and the practices associated with it. For example, the enclosure of common land for private use was understood as an “improvement” in the eighteenth century.

Recently, we have seen a push for evaluation systems to be used to sort and fire teachers—a supposed quick fix, but one that ignores the vast majority of dedicated educators. To be effective, an evaluation system must identify strengths and weaknesses, so that all teachers can get the necessary support to improve their practice. Your commitment and ability to improve defines your potential which is of interest to anyone who is a customer, employer, stakeholder as like a craftsman his ability to improve represents the marked improvement in his work from one to the next. In government Governments often use language proposing an improvement of processes or areas. In some places a business improvement district or tourism improvement district may be incorporated into urban zoning, with the enactment of laws intended to benefit businesses that are established in the area. An improvement trust, a type of legal trust created for the improvement of something,
