Uzbekistan has encountered severe budget shortfalls in its education program. The education law of 1992 began the process of theoretical reform, but the physical base has deteriorated and curriculum revision has been slow. A large contributor to this decline is the low level of wages received by teachers and the lack of spending on infrastructure, buildings and resources on behalf of the government. Corruption within the education system is also rampant, with students from wealthier families routinely bribing teachers and school executives to achieve high grades without attending school, or undertaking official examinations.
