As a young boy growing up in New York City, Neil deGrasse Tyson was fascinated by the sky above. Tyson followed his interest in space to become an icon in the field of astrophysics. As the director of the Hayden Planetarium, Tyson became well known for his role in the debate surrounding Pluto's status as a dwarf planet. In the tradition of Carl Sagan, Tyson educates the public as the host of the History Channel's television series Cosmos: A Spacetime Odyssey. Tyson's love of science and learning serves as a stellar example for kids and adults alike.

RAZ有严密的分级体系：根据全文词汇数、高频词词汇数与比例、低频词词汇数与比例、句子长度、句子复杂度、句式、插图信息量、思想深度、主题等多个角度，将整个阅读体系分为aa，A-Z共27个级别。
RAZ旨在帮助孩子找到适合孩子水平的级别，通过在同一级别下的大量阅读逐步提高孩子的阅读能力。
RAZ按难度分为27个级别，AA—C这4个级别对应幼儿园阶段; D—J这7个级别对应美国小学一年级;K—P这6个级别对应美国小学二年级;Q—T这4个级别对应美国小学三年级;U—W这3个级别对应美国小学四年级;X—Z对应美国小学五六年级(相当于国内高中毕业)。
