SCQF LEVEL 4 - National 4

Computing Science is vital to modern life – socially, technologically and economically – shaping our world and its future. Computing is embedded all around us, from devices in the home and workplace, to how we access education, entertainment, services and communication. Understanding computational processes and thinking is vital to many other fields including science, economics, business and industry.

Like it or not, you are living in the Digital Age! There are now estimated to be over three billion Internet users worldwide and in the last two years alone, 90% of the World’s data was generated. Given that this trend is only going to continue, there has never been a better time to study Computing Science. By studying Nat 4 Computing Science you will get an insight into many of the technologies that drive the modern world.  

Nat 4 Computing Science is composed of four taught units delivered from June to January, with the remainder of the academic year being devoted to coursework. 


Software Design & Development 

In this unit pupils develop their computational-thinking and practical problem-solving skills by designing, writing and testing a variety of computer programs using the Visual Basic Development Environment.  


Computer Systems 

In this unit pupils gain an understanding of how data and instructions are stored in binary form and learn about the basics of computer architecture. They will also gain an awareness of the environmental impact of computing systems and learn about the security precautions that can be taken to protect computer systems from the threats posed by computer viruses and hackers. 


Database Design and Development 

In this unit pupils will develop their practical problem-solving skills in database design and development through a range of practical and investigative tasks. Using their computational-thinking skills, pupils will design, create and query databases using MS Access.   


Web Design and Development 

In this unit pupils will develop their knowledge and understanding and practical problem-solving skills in web design and development by designing and creating websites with HTML code.

Information from pupils who have studied this course as to how they feel it was.

Ryan - S4

I picked computing science because I find it interesting and because it was the most interesting choice available.  


I have enjoyed learning how to code.   


Databases have been less interesting because I did them a lot in S3 admin   


It can open a lot of doors after school and it’s an interesting subject.
