I've added the phone number back here.
The challenge should not suggest to remove data like that, but if a change is suggested that you're not sure about then keep the previous value.

Same here with the name, which I've added back

Did the challenge really suggest the name be removed?!
I've added it back here

The possible values in the data for "Denomination" are:
Non-denominational : 2090
Roman Catholic : 360
Inter-denominational: 7
Episcopalian: 3
Jewish: 1
All schools have a denomination recorded.
In Scotland it seems that schools have to provide Religious Observance: https://www.gov.scot/publications/curriculum-for-excellence-religious-observance/
Paragraph 13 from that seems to be the key bit in explaining what non-denominational schools are like.

From that, I'm not sure that the face that there has to be some sort of religious observance would mean that a school should be tagged with a religion.

There are 23 objects tagged with variations of non-denominational in religion, according to taginfo, out of 1.4 million objects.

I could use a value like that, but I'm not sure whether it has more value, and "non-denominational" seems to have a fairly specific meaning in Scotland.

Happy to be corrected on any of the above

NSUL postcodes has this as CM0 8TE and that's also the postcode given on the website, am I alright to fix it?

And that's why I thought it would be reasonable here as that's sometimes the case near me too and all houses on both sides have the same postcode here.
As an aside, I've used postal_code:left and :right where postcodes are different on each side

> Roads (ways) don't really have full postcodes
They don't really have part postcodes either, so I'm not sure what utility that information has, whereas a full postcode could be routed to (if that was all that was known), rather than considering all buildings with the postcode.

Similarly here, I think B3 6JS should be B43 6JS and B3 6LG should be B43 6LG

Hi, what's your source for the postcodes here?
The ones that you've added as B3 6DT I think should be B43 6DT and likewise B3 6DX to B43 6DX

I feel like you should almost ignore the words used in the highway tag, and consider it confusing that they are similar to, but not the same as, the classification of UK roads by the government.
For the same sort of issue in other countries, see for example osm.wiki/East_Africa_Tagging_Guidelines
and note e.g. "In Kenya, despite the official designation International Trunk Roads, most of type A roads are not trunks as defined by OSM. The vast majority of Kenyan A roads must fall into the category highway=primary."

Ok, that seems to me like a partial postcode though and therefore much less useful than a full postcode

Hi, what's your basis for these changes?
Everything that I can see that you've changed from trunk to primary should actually be trunk.
See osm.wiki/Roads_in_the_United_Kingdom
for how we tag roads and e.g. the A167, A691 and A693 are all trunk roads by that definition, having yellow on green on the signs.
This can be confirmed by Mapillary photos, but I am also familiar with all of those roads.

A bit of research finds this duplicate: way/101155236
The postcode for this site seems to be PO13 8AS, so maybe it's this instead:
https://environment.data.gov.uk/public-register/waste-operations/registration/DB3901UD-T001?__pageState=result-all

Hi, just wondering what your source is for the postcode?
As that's showing as a long way away from here

No worries
I've set up a Map Roulette challenge to make adding detail to schools easier (which is what I used here)
Check it out if you're interested:
https://maproulette.org/browse/challenges/21922

Originally from https://get-information-schools.service.gov.uk/Establishments/Establishment/Details/136732 (available under OGL)
Then confirmed by the branding on the website
From the gov website you can see under links that the previous establishment didn't have Penrith in the name.

Hmm, I feel that postal_code is only for highways so I wouldn't like adding that.
Feel free to remove addr:postcode here

The postcode had actually previously been added by someone else here.
I agree that it seems like duplication having tags on the building as well as the site outline, but I'm not convinced that it's wrong for the school's postcode to be added to the school outline

Hi, thanks for adding all of these buildings.
It's best to use the address fields, rather than the name when adding the house numbers as that makes them more searchable. Then you can also add the street and postcode if you know them.
I'm fixing some round here.

Thanks

Sure, I think it's best to be explicit though
