In current research evaluation models, monitoring and impact evaluation are extended beyond peer-reviewed articles to include Public Communication of Science and Technology activities. Through an online survey, we analyzed the perceptions of relevance and degree of application of the altmetric indicators for the PCST of 51 sampled Brazilian federal universities. Perceptions of relevance and application of altmetrics proved to be an outlier in 26 indicators. 66.7% of respondents said they did not know the relevance of altmetrics for the PCST or considered it not applicable to the field. Regarding the perception of relevance, the indicator “Mentions tracked by altmetrics” received high relevance scores (7 and 9) from 21.5% of respondents. The indicator was also the least applied, with only one university (1.9%) using it. In addition, 45% of respondents reported having no intention of applying it, 41.1% intend to apply it in the long term, and 11.7% in the short term.
