Rank and test index range corresponding to Lance test: above 0L, the larger the number, the stronger the reading ability.

It should be noted that at the kindergarten level in early education, young readers who have just started reading independently, the test scores at the beginning of BR, the greater the number after BR, the weaker their reading ability; The smaller the number after BR, the better your reading ability.

Through two dimensions of semantic difficulty and syntactic complexity, this paper decomposes the sentence length and lexical frequency of the text based on LexileAnalyzer, and finally calculates the text.

Lance grading reading evaluation system provides early reading index for books with Lance index of 650L and below, thus providing more accurate matching. Early reading contains four criteria:

Structure, syntax, semantics, decoding.
