Words and Non-words Reading Competence Test (WNw-RCT). The WNw-RCT (Seabra & Capovilla, 2010) assesses competence in reading isolated words and is comprised of 70 test

items, each of which features a picture paired with a written word. There are seven different kinds of items (10 items of each kind). Figure 1 presents an example of each kind of item.

The items of correct regular and irregular words should be accepted and those with semantic errors or non- words must be rejected.

Test were used to assess 443 Brazilian students attending the 1st to 4th grades of elementary education, whose academic performance records were provided by the school at the end of the year. Analysis shows a significant effect of grade level on all variables and a pattern of higher scores in items that can be read by logographic strategy and lower scores for items that need orthographic processing.

This is a raw dataset and has to be cleaned-up before use
