The IReST differs from prior text charts that used single sentences by employing linguistically standardized paragraphs. They close a gap in the diagnostics of reading performance. The paragraphs are designed to resemble everyday life situations of reading continuous text, such as in books or newspapers. The level of difficulty corresponds to sixth-grade reading (10–12 years), which is comprehensible for teenagers and adults. Due to lower variance, measuring the reading time of a complete paragraph rather than a single sentence or random words is more reliable. Furthermore, it can provide some information about fluency, fatigue, and mistakes.

Article of Interest: Effects of home reading training on reading and quality of life in AMD – a randomized and controlled study


  • The first study for four languages was funded by the European Commission in the AMD Read Project. Two more languages were supported by the German Academic Exchange Office. The development of 11 more languages was supported by Alcon. An additional language supported by Allergan.
