SDG #5 is to “Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.”
Within SDG #4 are 10 targets, of which we here focus on Target 4.c:
By 2030, substantially increase the supply of qualified teachers, including through international cooperation for teacher training in developing countries, especially least developed countries and small island developing States
Target 4.c has one indicator:
Indicator 4.c.1: Proportion of teachers with the minimum required qualifications, by education level
As of 2019, the proportion of pre-primary teachers with the minimum required qualifications in the least developed countries (LDCs) was 63% and 72% in the small island developing countries (SIDS). For primary school teachers, the 2020 proportion was 79% for SIDS and 72% for LDCs and 86% worldwide. For each, the increase since 2015 was a couple percentage points. For lower secondary school in 2020, worldwide 83% of teachers had the minimum qualifications, 63% for LDCs and 75% for SIDS. For upper secondary in 2020, 89% of teachers in the SIDS had minimum qualifications, 85% worldwide, and 58% in LDCs.
