Frequently Asked Questions

What is a spike in college admissions?

A spike is demonstrated depth in one area—proven through projects, leadership, and measurable outcomes—that makes your application memorable and shows genuine passion rather than a scattered list of activities.

How many activities should a spike include?

A strong spike typically includes 3-5 activities that reinforce one clear theme, such as a summer research program, a related passion project, club leadership, and competition participation all in the same field.

When should I start building a spike?

Start exploring broadly in freshman year and begin focusing on your spike by sophomore year. By junior year you should have leadership roles and measurable impact in your chosen area.

Can I have a spike without winning awards?

Yes. A spike is about depth and impact, not just awards. Creating a project with real users, teaching others, publishing research, or building something that solves a real problem all demonstrate a strong spike.
