Reporting Category	Student Score	Collegeboard Score	Comments
Program Purpose and Function	1	0	The video and written description meets all requirements for showing and using the program.
Data Abstraction	1	1	The written response has clear information of a list and satisfies the requirements.
Managing Complexity	0	0	The given list does not manage the complexity in this program. Also makes an error when explaining the function of code.
Procedural Abstraction	1	0	Elaborates on the program and has required code segments.
Algorithm Implementation	1	1	Explains detailed explanation of code and meets all requirements.
Testing	1	1	Has 3 calls to the function which do different things.

Differences in Program Purpose and Function: I thought the project was descriptive enough when talking about the purpose, but Collegeboard wanted a very specific explanation of the purpose.

Example 2

Reporting Category	Student Score	Collegeboard Score	Comments
Program Purpose and Function	1	1	The video shows user input and the code working. The written description features specific descriptions of what it does and how it is useful. There is a clearly defined function of the program.
Data Abstraction	1	1	There are different code segments shown. There are accurate descriptions of the procedures and what is done. The list is defined and mentioned in the response.
Managing Complexity	1	1	The response shows how lots of data points need to be stored for the project.
Procedural Abstraction	1	1	The student developed produced call different functions. There is a call of the procedure replaceList. The written response accurately describes what the procedure does
Algorithm Implementation	1	1	The algorithm included has sequencing and selection. There is usage of an if statement to show usage of an if statement.
Testing	1	1	The function tests and shows proof of functionality. The video runs the code well and easily. The function has two separate calls.
