Numerous types of variable stars were classified using photometric data collected by Gaia. One of the new classes presented in the Gaia DR3 is the class of YSOs showing brightness variability. We analysed 79375 sources classified as YSO candidates to validate their young nature and investigate the completeness and purity of the sample. We cross-matched the Gaia DR3 YSO sample with numerous catalogues from the literature, including YSO catalogues based on optical and infrared data, as well as catalogues of extragalactic sources and Galactic variable stars. YSO catalogues were used to quantify the completeness of the Gaia DR3 YSO sample, while others were inspected to calculate the contamination. Among the 79375 potential Young Stellar Object candidates published in the Gaia DR3 variable star catalogue, the majority of these objects are distributed along the line of sight of well-known Star Forming Regions and the Galactic mid-plane. We found that the upper limit of contamination is 26.7%, depending on the external catalogue used for the estimation, but is ~10% in general, while the completeness is at the percent level, taking into account that the Gaia DR3 YSO sample is based on sources that showed significant variability during the data collection period. The number of sources in our sample that were never catalogued before as YSO candidates is in the order of ~40000 objects.2023A&A...674A..21Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/674/A21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/352 : Distances to 1.47 billion stars in Gaia EDR3 (Bailer-Jones+, 2021)I/355 : Gaia DR3 Part 1.
