UK Level 7/8 Diploma Questions

[lincolnlawyer]

After scouring through the forum for answers to a question unrelated to this thread, I came across the term Level 7/Level 8 Diploma several times. AFAIK Level 8 is doctoral studies so it’s a different story, but Level 7 in the UK OFQUAL system is essentially Master’s level. 

So what is the difference between a Level 7 diploma and a postgraduate diploma? 

I do see a general trend that universities tend to name their programs “postgraduate diploma”, whereas education providers such as LSIB or Cambridge Management and Leadership School tend to name their programs “level 7 diploma”. 

Are there any difference in the two? Are they recognized equally outside the UK?
