COMMON APP FIELD NOTES · HOURS / WEEK

The number looks simple. The year behind it is not.

A student can spend 8 hours a week on an activity in October, 22 during build season, 46 during a summer job, or 60 during one extraordinary tournament week. The Common App still gives you one box.

CURRENT FIELD LANGUAGE

Hours spent per week

“Share how much time you typically spend during the busiest parts of the year. It’s okay to use your best guess.”

Tap the underlined words. The answer is hidden in the wording.

SHORT ANSWER

Do not default to a full-year average. But do not automatically report the single most extreme week either. The most defensible reading is the hours you typically spend in a genuine, recurring busy period for that activity.

That is an interpretation of the wording—not a published Common App formula. Common App explicitly allows a best estimate, and current applicants are encountering genuine ambiguity in how to translate seasonal schedules into one number.

01

THE FALSE CHOICE

Average vs. busiest week is the wrong binary.

The phrase contains two instructions at once. “Busiest parts” points you away from a whole-year average. “Typically” points you away from a freak one-off maximum.

10

Whole-year average

Useful for understanding total time, but it can flatten a real season when the form specifically asks about busier periods.

NOT THE DEFAULT

22

Typical busy-period week

A representative week inside build season, competition season, summer full-time work, rehearsal season, or another sustained peak.

BEST FIT TO THE WORDING

46

Single extreme week

A championship trip, conference weekend, overnight hackathon, launch deadline, or one unusual week can be real without being “typical.”

USE CAUTION

THE IVY INSTITUTE RULE OF THUMB Find the peak period, then report a representative week inside it.

02

THE PEAK DETECTOR

A peak is a pattern. A spike is an exception.

Imagine your activity as a year-long signal. The question is not “what was the highest point?” It is “what did this activity normally demand when it was truly busy?”

REGULAR

6–8 hrs

BUSY PERIOD

18–22 hrs

ONE-OFF

41 hrs

01

Did this higher schedule last for multiple weeks?

02

Would another week in that same season look roughly similar?

03

Was the intensity part of the normal cycle of the activity?

04

Could you explain the number confidently if someone asked?

This is also why what counts as a meaningful extracurricular is broader than school clubs alone: jobs, caregiving, research, independent work, athletics, and online projects can all have very different seasonal rhythms.

03

RUN THE SEASONS

What should you enter for common seasonal activities?

Choose an activity. The calendar will show the difference between ordinary time, a real busy period, and an exceptional spike.

Robotics Varsity sport Seasonal job Research Summer program

BUILD SEASON

Robotics: 6 hours normally, 20 during build season, 34 at one championship.

If 18–22 hours is normal across several build-season weeks, that range better matches “typically … during the busiest parts” than either a 9-hour annual average or a single 34-hour championship week.

LIKELY APPROACH ≈ 20 hrs/week Use the recurring build-season pattern; keep the one-off championship spike in context.

Hours establish scale; they do not establish meaning. The stronger activities list still needs to show what changed because you were there, not simply how long you were there.

04

THE 168-HOUR CHECK

“But if I put 30–60 hours, won’t it look fake?”

Not automatically. A summer job can genuinely be 40 hours a week. Band camp can genuinely occupy most of a day. A tournament trip can consume a weekend. The credibility problem begins when the numbers imply schedules that cannot plausibly coexist.

168hours exist in every week

Sleep 56 School + commute 40 Homework 14 Job / family / other 10

Committed before this activity48 hours remain

Do not add every activity’s peak hours as though all peaks happened in the same week.

Robotics may peak in February, tennis in April, research in July, and a job during winter break. The new wording can make the sum of all listed “hours/week” look impossible even when each individual peak is true.

The goal is a coherent application, not a time-sheet competition. That same principle sits behind Application Identity™: every data point should help the reader understand one real student rather than manufacture a busier-looking résumé.

05

INTERACTIVE · BUSY-PERIOD LAB

Test your own activity before you type the number.

This tool does not calculate an official Common App answer. It helps you separate a year-wide average, a sustained busy period, and a one-off spike so you can make a defensible estimate.

Activity name

Regular period

Hours / week Weeks / year

Recurring busy period

Hours / week Weeks / year This schedule is typical across a genuine busy stretch.

Exceptional spike

YOUR YEAR, THREE WAYS

Whole-period average10.2hrs / active week

Single highest week34hrs / week

Wording-aligned estimate20hrs / week

Your 20-hour schedule repeats across an 8-week busy period, so it is a stronger fit to “typically … during the busiest parts” than the 34-hour one-off spike.

06

THE SECOND BOX

What about “weeks spent per year”?

This is where students are most likely to accidentally create a misleading picture. The hours prompt explicitly refers to the busy part of the year. The separate weeks field asks how many weeks you spent on the activity.

HOURS / WEEK Peak-period intensity

Use a representative week from the activity’s genuine busy period.

→

WEEKS / YEAR Total participation duration

Do not erase quieter weeks simply because the hours box is describing the busier stretch.

EXAMPLE

Summer + school-year job

8 hrs/week during school · 35 hrs/week for 10 summer weeks · worked 46 weeks total.

Hours/week≈35 Weeks/year46

Important: that pairing should not be read as “35 × 46 = 1,610 hours.” The hours field is now framed around the busy period, so multiplying the two fields can manufacture a total the student never claimed. When the contrast is large enough to confuse a reader, use a few characters in the description to show the seasonality.

If you are still building the full application, our guide to what to do when the Common App opens explains how the activities list fits into the larger application workflow.

07

CLARITY BUILDER

When the number cannot tell the whole truth, let six words do the work.

You usually do not need a paragraph explaining your hours. A compact phrase can prevent a seasonal activity from being misread.

Use extra context when…

your peak is dramatically higher than your baseline the activity changes structure by season a job moves from part-time to full-time travel or overnight events create unusual spikes two activities alternate rather than overlap the number would otherwise look implausible

Do not spend the 150-character activity description defending every estimate if that space is better used for impact. Strong application strategy decides what each field needs to accomplish; that is part of the broader work in Predictive Admissions™ and our college admissions and application services.

08

FINAL QUALITY CHECK

Before you submit the number, make sure you can defend the story behind it.

The Common App says a best guess is okay. “Best guess” does not mean careless guess; it means an honest estimate from imperfect records.

My number represents a real busy period, not just the most extreme isolated week. I did not force a full-year average when the form asks about busier parts of the year. My weeks/year reflects how long I actually participated. If the seasonal contrast is unusually large, I added concise context where useful. If someone asked how I estimated this number, I could explain it without changing my story.

0 / 5 · Run the credibility check.

THE BOTTOM LINE

Report the typical peak, not the mathematical average and not the record high.

For a seasonal activity, ask: “During the stretch when this activity was genuinely at its busiest, what did a normal week look like?” That is the number the current wording most naturally asks you to estimate.

EDITORIAL NOTE · AUGUST 2026

The 2026–27 Common App interface is being reported by applicants with the wording quoted above. Public Common App resources confirm that the Activities section is designed to communicate meaningful experiences and allows additional context, but Common App has not published a public mathematical formula for converting variable schedules into this field. This guide therefore separates the literal prompt from The Ivy Institute’s interpretation of how to answer it credibly.
