The International Association of Transnational Universities (IATU) is an organization that provides accreditation to institutions, often following the GAAP standards. BQS likely refers to the Boards for Quality Standards, an independent body associated with IATU that focuses on quality assurance in higher education. IATU is a network for transnational universities, which are institutions that operate across national borders. 

Here's a more detailed explanation: 

• International Association of Transnational Universities (IATU):
  IATU is a global network that accredits and recognizes transnational universities, which are higher education institutions that operate in more than one country.
• Boards for Quality Standards (BQS):
  BQS is an independent organization that is likely affiliated with IATU and focuses on quality assurance within higher education, ensuring that accredited institutions meet certain standards.
• Transnational Education:
  This refers to higher education programs or institutions that operate across national borders, often involving partnerships or branches in different countries.
• Accreditation:
  IATU and BQS provide accreditation to institutions that meet their established standards, signifying that the institution meets certain quality benchmarks.

Essentially, IATU and BQS work together to promote quality and recognition within the field of transnational higher education. ​
