The Kenya Publishers Association has come out to refute claims that the books in the market have not met the required quality standards.
Lawrence Njagi chairman of the association says all books go through rigorous vetting by KICD to ensure that they have met the required standards.
Njagi says the two of the controversial books with errors are produced in the USA and Ghana.
According to Njagi the association is working with the government to ensure that all the books that get into the country have met the required standards
Njagi also noted that the government has not issued guidelines on the books to be published for use by the students joining grade four next year as they have already been tested through the roll out programme which covered grade one to three
