I have the achievement "Youngster" in progress with a peculiar description:

I've definitely caught more than 1 Rattata. Just look at my candies for proof:

Am I missing something here or is this achievement broken?

  • I was wondering the same thing actually - I intentionally caught several Rattata and my progress didn't increase on this badge.

  • I remember the tooltip to say Rattata of a particular weight

  • @Insane The tool tip said so I believe. Not in a position to double check it right now ;)

    Youngster was a name for a common type of trainer you would face in Pokémon Red / Blue / Yellow

The Youngster achievement is actually awarded for catching some number of Rattata below a certain weight.

The achievement previously stated "Caught {0} Rattata weighing at most {1}". In many programming languages, {0} and {1} are just ways to substitute numbers into some text. It seems that Niantic simply messed up the description, even though it tracks correctly.

A screenshot may be found at Timelord64's answer to the question I've got an “XS” Pokémon. Is it special?, reproduced here: "Youngster: Caught {0} Rattata weighing at most {1}."

The badge is called BADGE_SMALL_RATTATA in the data dump. The data dump lists its targets as \0032\254\002, which translates to requirements of 3, 50, and 300. There's no indication for weight, but I suspect it just requires XS Rattata.

Regarding XS Rattata specifically, I hypothesise that a Rattata is XS if it is 2 standard deviations below the mean. The mean for Rattata is 3.5 kg, and the standard deviation is 0.4375 kg, so you should be getting it for Rattata below 2.625 kg. (The game only shows two digits for weight, so this falls between 2.62 and 2.63 kg. I hypothesise this because I have a 2.4 kg XS Rattata, and a 2.75 kg regular Rattata.)

  • This answer would be complete with some details as to what that weight is, maybe a screenshot of the old text? This could be heresy.

    The description just says "Caught 11 Rattata" for me - no mention of weight. Are you saying it used to be with the weight note, but that was removed in an update?

    Incidentally, the name of the achievement is probably a reference to Youngster Joey: knowyourmeme.com/memes/youngster-joey

    It appears in the most recent app update - marked "minor text fixes" - this badge's description is now "Caught x tiny Ratatta"

    I have just confirm that both Weight and Height have to be XS to get a younger Rattata as for Magikarp XL

Items {
  TemplateId: "BADGE_SMALL_RATTATA"
  Badge {
    BadgeType: BADGE_SMALL_RATTATA
    BadgeRanks: 4
    Targets: "\0032\254\002"
  }
}

Although it doesn't say so in the description anymore the badge is supposed to be awarded for catching lightweight Rattata. The name BADGE_SMALL_RATTATA is pretty obvious. It's the opposite of the Magikarp badge, where you need big catches to get it.

Some communities confirm the text to be bugged, some say it's the badge itself, that's bugged. My recent Rattata catches showed a working badge with incorrect tool tip text.

it say: Caught [0] Rattata weighing at most 1 so the rattata you catch must be light weight

Tiny Rattata is any Rattata with a CP of 10 or less. As you increase your level by XP, tinny rattatas become harder to find

  • It's actually designated by the XS you see on size/weight. See the accepted answer. CP doesn't change whether or not it's tiny or large.

  • There are no <10 CPs.
