From the point of view of the objectives and scope of the assessment: 

• Absolute assessment – Allows to determine whether the project is cost-effective and should be implemented. 
• Relative assessment – Involve comparing and ranking multiple projects before deciding on some of them. 

Due to the timing of the assessment: 

• Prospective evaluation – This takes place at the initial stage of project preparation. 
• Retrospective assessment – Carried out after completion of the project. 

From the standpoint of execution time: 

• Short-term project assessment – For projects with a duration of less than one year 
• Long-term project assessment – Requires more sophisticated methods of assessing the effectiveness, using dynamic methods.
