As the PTE requirement depends upon the purpose of taking the exam, there is no average PTE score as such.
The overall score in PTE Academic is a combination of the scores achieved in all the 4 individual skills, and not the average of the scores.
As per the Common European Framework of Reference for Languages (CEF), the PTE score ranges as per proficiency levels are:
| 
			 CEF Level  | 
			
			 Proficiency Level  | 
			
			 PTE Academic score range  | 
		
| 
			 A2  | 
			
			 Basic User  | 
			
			 24 to 42  | 
		
| 
			 B1  | 
			
			 Independent User  | 
			
			 36 to 58  | 
		
| 
			 B2  | 
			
			 Independent User  | 
			
			 51 to 75  | 
		
| 
			 C1  | 
			
			 Proficient User  | 
			
			 67 to 84  | 
		
| 
			 C2  | 
			
			 Proficient User  | 
			
			 80+  | 
		
The CEF is used as a benchmark for reference to understand scores in any language qualification exam.
