Small schools with limited resources in Thailand have combined classes.

They have pupils from 2 classes studying together under one teacher and those in one class are taught first while the other class is doing exercises and wait for their turn by the same teacher.

Those implementing this teaching arrangement are Pha Khwang Witthaya School's Khwae Wuadam branch in Chiang Rai's Muang District (with 39 students and three teachers), and Pasak Ngam School in Chiang Mai's Doi Saket district (with nine students and two teachers). At Pha Khwang Witthaya, Prathom 1 (Grade 1) has been combined with Prathom 2 (Grade 2), Prathom 3 with Prathom 4, and Prathom 5 with Prathom 6. Also, Pasak Ngam has combined Prathom 1, 2 and 3, but Prathom 4, 5 and 6 have studied in the same combined class.

Those that are located in isolated areas like the Pha Khwang Witthaya in a mountainous area and Pasak Ngam in an area where a dam separates it from other parts of the district, they are considered small schools that cannot be merged with bigger ones are closed down, although Education Minister Phongthep Thepkanjana has issued a policy to merge small schools. He recently visited both schools to listen to their problems before deciding how to provide further assistance to small schools that are unable to merge with larger ones due to their isolated locations. The combined classes idea was conceived by the Office of Basic Education Commission to assist small schools cope with the problem of limited resources.

However, the teaching process was much slower than in schools with proper resource. A classroom of the school branch is noisy in the morning as pupils recite multiplication tables, but in the afternoon one can hear the sound of looms with which they weave cloth. This is how in which all the 39 pupils at Pha Khwang Witthaya School's Khwae Wuadam branch in Chiang Rai's Muang district enhance their learning. The students are taught core curriculum subjects like maths, science, Thai and English language in the morning. In the afternoon, the classes turn into occupational training rooms where local residents pass on their occupational skills to the pupils.

The number of teachers there is not enough to teach every subject to all the students. The school has also made use of resources from it's surrounding communities, including natural learning methods and locals who volunteer to teach students on how to grow vegetables and raise hens for eggs.

After visiting both schools, the ministry would provide them with more resources for the sake of the students. The school would be equipped with a satellite for distance learning and temporary teachers would be assigned to teach subjects with which local teachers were not so familiar. Locals would also take part in teaching the pupils weaving and basketry, so that students can apply them soon when start to work on their own. The ocal people and local administrative organisations were urged to support the schools, as the budget from the ministry alone is not enough.
