In Year 2 (October 2020–September 2021), the Program designed and implemented a Status of Instruction Study (SIS) to shed light on teachers’ knowledge, attitudes and beliefs, skills, and behaviors; the resources available at the school level and for the targeted subjects; and how these resources are used. The Program also designed a Teacher Support System Study (TSSS) to examine the existing teacher support system and identify teacher support challenges and opportunities. The TSSS results will be used to create a Program TPD approach. The TSSS data collection process was integrated into the second phase of the SIS data collection process, which occurred in mid-2021. This was done because both studies targeted the same respondents: teachers, school directors, and methodologists. The TSSS, like the SIS, was originally intended to include in-person interviews. However, because of the prolonged difficulties caused by the coronavirus disease 2019 (COVID-19) pandemic, data collection was done remotely. This report presents the TSSS methodology and findings from online surveys administered to more than 4,100 teachers, 183 school directors, and 131 methodologists from all regions of Uzbekistan, including the Republic of Karakalpakstan and Tashkent City.
