This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. There are no shareholder fees (fees paid directly from your investment) when you buy and sell shares of the Fund. Future expenses may be greater or less. You may be required to pay commissions and/or other forms of compensation to a financial intermediary for transactions in Institutional Class shares of the Fund, which are not reflected in the tables or the Example below. Please contact your financial intermediary about whether such a commission may apply to your transaction.

Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock
The example that follows is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated whether or not you redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year, that the Fund’s operating expenses remain the same and that the Expense Limitation is never terminated by the Fund’s Board. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Portfolio Turnover [Heading] oef_PortfolioTurnoverHeading Portfolio turnover
Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal investment strategies of the Fund
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
To achieve the Fund’s investment objective, the Adviser invests the Fund’s assets in a diversified core portfolio of U.S. equity securities with favorable growth prospects, selected using a disciplined quantitative optimization process. Under normal circumstances, the Fund purchases companies with market capitalization greater than $15 billion at the time of purchase and the Fund ’s portfolio will generally consist of 30 to 70 positions. However, the Fund may invest in small, mid or large capitalization companies, including foreign companies.
The Fund invests primarily in companies that the Adviser believes demonstrates attractive risk-adjusted-return potential. The investment strategy combines fundamental market data with proprietary portfolio construction techniques designed to identify securities with favorable characteristics, including earnings quality, valuation, momentum, financial strength, and diversification benefits. The Fund’s optimization framework evaluates expected return, volatility, and correlation among holdings to construct a diversified portfolio intended to improve overall portfolio efficiency and potential return while managing downside risk. There are no set limitations of investments according to a company’s size or to a sector weighting.
During the investment selection process, the Adviser utilizes the rankings of companies by the Value Line Timeliness™ Ranking System (the “Ranking System”) to assist in selecting securities for purchase. The Ranking System is a proprietary quantitative system that compares an estimate of the probable market performance of each stock within a universe during the next six to twelve months to that of all stocks within that universe and ranks stocks on a scale of 1 (highest) to 5 (lowest).
The Adviser may sell securities for a variety of reasons, including when a company’s business fundamentals deteriorate or a company’s valuation has become less attractive in relationship to the company’s future growth prospects. Other reasons include to secure gains, limit losses or redeploy assets into more promising investment opportunities.
The Adviser has discretion in managing the Fund, including whether and which ranked stocks to include within the Fund’s portfolio, whether and when to buy or sell stocks based upon changes in their rankings, and the frequency and timing of
rebalancing the Fund’s portfolio. The Adviser will determine the percentage of the Fund’s assets invested in each stock based on the stock’s relative attractiveness taking into account the potential risk and reward of each investment.

Risk [Text Block] oef_RiskTextBlock Investing in any mutual fund involves risk, including the risk that you may receive little or no return on your investment, and that you may lose money.

Risk [Text Block] oef_RiskTextBlock An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.
Value Line Select Core Fund, Inc. | Growth Style Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Growth Style Risk. Growth stocks may be more volatile than other stocks because they are generally more sensitive to investor perceptions and market movements. In addition, growth stocks as a group may be out of favor at times and underperform the overall equity market for long periods while investors concentrate on other types of stocks, such as “value” stocks.
Value Line Select Core Fund, Inc. | Market Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Market Risk. The chief risk that you assume when investing in the Fund is market risk which is the possibility that the securities in a certain market will decline in value because of factors such as recessions, changes in interest rates, global trade policies, war, terrorism including cyber terrorism, natural and environmental disasters as well as public health emergencies. Market risk may have a material impact on a single issuer, an industry, a sector of the economy or the market as a whole and could be significant and cause losses.
Value Line Select Core Fund, Inc. | Equity Securities Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Equity Securities Risk. Equity securities represent ownership in a corporation and their prices fluctuate for a number of reasons including issuer-specific events, market perceptions and general movements in the equity markets. The resulting fluctuation in the price of equity securities may take the form of a drastic movement or a sustained trend. If an issuer is liquidated or declares bankruptcy, the claims of owners of bonds will take precedence over the claims of owners of common stocks. Historically, the prices of equity securities have fluctuated more than bond prices.
Value Line Select Core Fund, Inc. | Sector Allocation Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Sector Allocation Risk. A sector is a group of selected industries within the economy, such as technology. The Fund may be overweighted or underweighted in certain sectors, which may cause the Fund’s performance to be more or less sensitive, respectively, to developments affecting those sectors.
Value Line Select Core Fund, Inc. | Focused Portfolio Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Focused Portfolio Risk. Because the Fund may invest a significant portion of its assets in a small number of securities, the Fund’s net asset value may be more volatile and the Fund’s investments may involve more risk than investing in a fund that holds a greater number of securities.
Value Line Select Core Fund, Inc. | Small and Mid-Sized Company Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Small and Mid-Sized Company Risk. Investments in small and mid-sized companies may involve greater risks than investments in larger, more established companies — as a general rule, the smaller the market capitalization of the company, the greater the risk. As compared to larger companies, small and mid-sized companies may have limited management experience or depth, limited ability to generate or borrow capital needed for growth, and limited products or services, or may operate in less established markets. Accordingly, small and mid-sized company securities may be more sensitive to changing economic, market, and industry conditions and may be more
volatile and less liquid than equity securities of larger companies, especially over the short term. Small and mid-sized companies also may fall out of favor relative to larger companies in certain market cycles, causing the Fund to incur losses or underperform.
Value Line Select Core Fund, Inc. | Ranking System Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Ranking System Risk. The Adviser’s use of the results of the Ranking System in managing the Fund involves the risk that the Ranking System may not have the predictive qualities anticipated by the Adviser or that over certain periods of time the price of securities not covered by the Ranking System, or lower-ranked securities, may appreciate to a greater extent than those securities in the Fund’s portfolio. Quantitative models like the Ranking Systems may not work as anticipated, potentially resulting in lower investment performance or losses to the Fund.
Value Line Select Core Fund, Inc. | Active Management Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Active Management Risk. Because the Fund is actively managed, its investment return depends on the ability of the Adviser to manage its portfolio successfully. There can be no guarantee that the Adviser’s investment strategies will produce the desired results or that the investment objective of the Fund will be achieved.
Value Line Select Core Fund, Inc. | Foreign Investments Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Foreign Investments Risk. Investing in foreign securities poses additional risks. The performance of foreign securities can be adversely affected by the different political, regulatory and economic environments in countries where the Fund invests, and fluctuations in foreign currency exchange rates may also adversely affect the value of foreign securities. These risks tend to be more volatile in emerging markets (as compared to the U.S. market or developed foreign markets).
Value Line Select Core Fund, Inc. | Market Disruption Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Market Disruption Risk. Markets may be impacted by negative external and/or direct and indirect economic factors such as pandemics (including COVID-19), natural disasters, global trade policies and political unrest or uncertainties. The adverse impact of any one or more of these events on the market value of Fund investments could be significant and can affect the economies of many nations, individual companies and the market in general. The Adviser cannot predict the likelihood of occurrence or the effects of similar disruptive events in the future on the U.S. and other economies, or the investments in the Fund’s portfolio or the potential for success of the Fund.
Value Line Select Core Fund, Inc. | Cybersecurity Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Cybersecurity Risk. As the use of technology becomes more prevalent in the course of business, the Fund becomes more susceptible to operational, financial and information security risks resulting from cyberattacks and/or technological malfunctions. Successful cyberattacks and/or technological malfunctions affecting the Fund or its service providers can result in, among other things, financial losses to the Fund and its shareholders, the inability to process transactions with shareholders or other parties and the release of private shareholder information or confidential Fund information. While measures have been developed which are designed to reduce the risks associated with cybersecurity, there are inherent limitations in such measures and there is no guarantee those measures will be effective, particularly since the Fund does not directly control the cybersecurity measures of its service providers, financial intermediaries or companies in which it invests or with which it does business.

Performance Inception Date oef_PerfInceptionDate May 01, 2020
[1] EULAV Asset Management (the “Adviser”) has agreed to pay or reimburse certain class-specific fees and expenses incurred by the Institutional Class so that the Institutional Class bears its class-specific fees and expenses at the same percentage of its average daily net assets as the Investor Class’s class-specific fees and expenses (excluding 12b-1 fees and any extraordinary expenses incurred in different amounts by the classes) (the “Expense Limitation”). The Adviser may subsequently recover from assets attributable to the Institutional Class the reimbursed expenses and/or waived fees (within 3 years from the month in which the waiver/reimbursement occurred) to the extent that the Institutional Class’s expense ratio is less than the Expense Limitation or, if lower, the expense limitation in effect when the waiver/reimbursement occurred. The Expense Limitation can be terminated only with the agreement of the Fund’s Board.
