How we build this list and where its facts come from

Where the facts come from

We read each place's website and note what it offers children: ages, weekly times, prices with the period they cover, languages, trial classes and whether an adult must stay.

The address, the map point and the opening hours may also come from the place's Google Maps listing. A club's membership of a federation may come from the club list that federation publishes. A place with no website of its own may be listed from its Google listing alone, when the listing itself says it is for children; its page then gives only the address and opening hours.

Each fact is stored with the address of its page, the reading date and a short quote in that page's words. Directories, news, booking platforms, social networks and reviews do not count as sources.

Source marks

There are three marks. Published by the place: its own website. Google listing: its Google Maps listing. Federation list: the club list of a sports federation.

A place's page shows the mark and the date next to each fact, so you can see who said it and how long ago.

When a fact is missing

If the pages we read do not give a fact, the place's page marks it as not published and the table shows a dash. “Not published” speaks only of those pages.

No gap is filled by guessing. A school grade, such as third of primary, is never turned into an age. Each price keeps the period the place gives, and we do one sum only: the per-class price marked ≈, the cost of a package or a whole workshop divided by the number of classes in it.

Class times and opening hours

The table has two time columns. Dates and times: the days and hours of a workshop or an afternoon of care, and the dates of vacaciones útiles, as the place publishes them. Opening hours: when the branch is open, often from its Google listing.

A branch can be open with no group for a given age at that hour. A row with opening hours only goes below the line, under a heading that says why.

The after-school pages look at Monday to Friday between 15:30 and 19:30: from the end of the school day to the hour many families collect their children. A workshop counts if one of its groups starts inside that stretch; care counts if its hours cover the whole of it.

What we do not assess

No place, teacher, coach or programme gets a mark, a score or a rank.
We do not visit the places: every fact comes from a published source.
We give no opinion on how well a place teaches, coaches or cares.
We do not know whether a group has free spots; ask the place.
We do not check municipal licences, insurance or staff backgrounds.
Prices appear as published, with their period and date, unconfirmed with the place.

Right of reply

Do you run a place on the list and see a fact that is wrong, incomplete or old? Send the right one with the form and a link to the page where it appears.

If the place's own pages back the correction, it goes into the next update and is noted in the log of changes. A place that closes keeps its page, marked as closed, and leaves every table.

You can also ask for a place you run to leave the list: choose “Ask for a place to leave the list” in the form and leave a contact that shows you run it. Within a month we remove the place, its page and its rows in the data files.

Dates and updates

Each place's sources are read again within 6 months of the last reading. A price published for a period now over stays on the place's page with that period, but neither the filters nor the summary line count it.

How it is funded

Being listed costs nothing, and no payment changes a row or its position in the table.

A place's page may carry a link to Zartrace, a service affiliated with this catalogue and marked as such. Clicks on contact buttons are counted as totals only, with no personal data.

Open data

The whole catalogue can be downloaded as JSON, one record per place, and as CSV, one row per programme. Both files carry the sources, marks and dates, and state their licence.

Districts, distance and map

The areas are the districts of the city families cross during the week, most of Lima Metropolitana and Callao, from Comas and Los Olivos to Villa El Salvador and from La Punta to Ate and La Molina. The district of Lima appears as Cercado de Lima and Santiago de Surco as Surco, the names families use. Each branch goes to the district whose boundary holds its point on the map; a branch in a district outside the city, such as Carabayllo or Cieneguilla, stays in that district.

Distance is measured in a straight line from the point you choose to the nearest branch and rounded to the half kilometre. Your location is requested only when you press the button, and it never leaves your browser.
