Primary Outcomes (explanation)
End point 1:
(i) Library-using and non-textbook reading behaviours
Constructed from the questionnaires asking
1. “Do you know where the library is?”
(a) Yes
(b) No
2. “Do you find library as a relaxing reading space?”
(a) Yes
(b) No
3. “Do you find library as a peaceful place you can focus?”
(a) Yes
(b) No
4. “How often do you read non-textbooks?”
(a) Every day
(b) Some days
(c) Never
As reading every day is a small fraction of the answers, we combine (a) and (b) to constitute the variable of reading some days or every day and assign the value 1. Never reading non-textbooks, in contrast, is assigned to the binary measure of 0.
5. “Do you enjoy reading non-textbooks?”
(a) Yes
(b) No
(c) Just so-so
As the number of students who answer NO is very small, we combine Just so-so and No to create the binary measure of 0. For those who enjoy it, we assign the value of 1.
(ii) Cognitive outcomes in terms of literacy of Thai language tested by the Programmes’ own devised Thai reading and writing tests for each grade.
Constructed from the raw scores of each student, we construct a z-score based on the normalisation of subtracting the mean and dividing it by the standard deviation of the treatment group of the same grade. The tests were also piloted in a school in the neighbouring Payao Province to test the validity and the distribution of the raw scores.
(iii) Non-cognitive outcomes that can be related to reading – attentiveness
The construction of the binary variable is based on the questions in Eysenck test (Eysenck, 1984) that are relevant to school-domain attentiveness.
1. “Do you usually work quickly without bothering to check answers?”
(a) Yes
(b) No
2. “Do you sometimes put down the first answer during the test and forget to check it later?”
(a) Yes
(b) No
(iv) Non-cognitive outcomes that can be related to reading – empathy
The ordinal variable construction is based on the following questions.
1. “When reading books or watching animation, I feel bonded and understand the feelings of the characters.”
(a) Yes, that is very true.
(b) Yes, but just sometimes.
(c) Never.
2. “Whenever I have a chance, I always help others.”
(a) Yes, that is very true.
(b) Yes, but just sometimes.
(c) Never.

End point 3: Long-run cognitive outcomes after three years from the start of the intervention
Using reading and writing Thai language test based on nationalised tests by the Ministry of Education.
From the raw scores of each student, we construct a z-score based on the normalisation of subtracting the mean and dividing it by the standard deviation of the treatment group of the same grade. For Grades 4 to 6 students, who were in Grades 1 to 3 at the start of the intervention, the scores cover four categories, (i) reading aloud, (ii) reading comprehension, (iii) total reading, and (iv) writing. As some schools have a secondary-school-level extension, we also test Grades 7 to 9 students, who were in Grades 4 to 6 at the beginning of the intervention. Their scores span two categories, (i) reading comprehension and (ii) writing.
End point 4: Long-run cognitive outcomes when students from each grade reach grade 6.
Using the nationalised O-NET exam on Thai language, Mathematics, Science, and English to test the long-term effects whether reading can have a spillover impact on the proficiency of other subjects that are also based on the ability to read, understand and analyse, and concentrate. For each subject, From the raw scores of each student, we construct a z-score based on the normalisation of subtracting the mean and dividing it by the standard deviation of the treatment group of the same batch.
