Many CSV Files Containing Common Names - Combine Across Sheets To One Line

I work for schools use data to guide teachers practices in the classroom. My main function is to mine down through data for kids that teachers focus on specific skills with specific children.

I start with a big conference each summer. By hand I combine, by student name, the data collected over the past school year. We then tear down to student levels setting goals based on statistical analysis. I need to combine across all of these csv files in a way that appends the data from each into one line per kid. I thought that 'vlookup' or 'index, match' might do it. I don't know.
