According to Leonardo Carvajal from the Assembly of Education in Venezuela, the collection of books had "become a vulgar propaganda". Venezuelan historian Inés Quintero stated that in all social science books, "there is an abuse of history, ... a clear trend favoring the current political project and the political programs of the Government". Geometry professor Tomas Guardia of the Central University of Venezuela stated that "the math textbook is so problematic, there's a good chance this book is also full of errors and propaganda" after he spent months inspecting math textbooks and noticed simple errors, such as calling a shape with four sides a square when it could also be a rectangle or a rhombus. According to the Center of Reflection and Education Planning (CERPE) from a 2014 study by Alfredo Keller "et al"., 77% of Venezuelans rejected the implementation of education based on a socialist ideology.
